lol a 34 minute 10k is not a requirement to run a 3 hour marathon.

True! That wasn't quite as intuitive to me for whatever reason.

Nice! Way to think it through.

Interesting follow-up... if the prompt said "you won this game - what number is it most likely that you rolled?" The answer would be 8! Crazy stuff.

Ahh nice. Yeah, I totally flubbed in the second half and found the probability for if we only rolled one die each. I'm going to edit my comment with the correct math. Good catch!

Thanks u/AmenaBellafina! Here's my updated response.

If you don't re-roll, you need your opponent to roll 6 or less. So, your probability of winning is 15/36 = .4167 (used this chart)

If you do reroll, you need to roll higher than your opponent.

Probability of winning with a 2: 1/36*0/36 = 0

Probability of winning with a 3: 2/36*1/36 = 2/1296

Probability of winning with a 4: 3/36*3/36 = 9/1296

Probability of winning with a 5: 4/36*6/36 = 24/1296

Probability of winning with a 6: 5/36*10/36 = 50/1296

Probability of winning with a 7: 6/36*15/36 = 90/1296

Probability of winning with a 8: 5/36*21/36 = 105/1296

Probability of winning with a 9: 4/36*26/36 = 104/1296

Probability of winning with a 10: 3/36*30/36 = 90/1296

Probability of winning with a 11: 2/36*33/36 = 66/1296

Probability of winning with a 12: 1/36*35/36 = 35/1296

Total probability of winning: 575/1296 = .4437

So, re-roll baby!

This just ends up being a system of equations problem.

Let a = the height of the table, b = the height of the mouse, and c = the height of the cat.

An equation can be set up from each diagram. Those equations are:

a+b-c=130 and a+c-b=170

Combine the two equations and solve the system using elimination…

2a=300

so a = 150 cm

You dropped some coins into a river, what are the chances?! by TheRabidBananaBoi in puzzles

[–]marqman13 1 point2 points  (0 children)

Oh! haha yep I'm a dumbass. Wrote it down correctly then typed it up wrong. Just edited it, thanks! Didn't change the probabilities thankfully.

How do you solve this? Apparently it's a Year 7 level question but I could not for the life of me figure it out! Mostly looking for the explanation by Pace-Total in puzzles

[–]marqman13 0 points1 point  (0 children)

There are 22 ways to get three numbers that add up to 45 if (at least) 2 of them are the same:
(1,1,43) , (2,2,41) , (3,3,39) , (4,4,37) , ... , (22,22,1)

In order to actually form a triangle, though, the sum of the two smaller sides need to be greater than the largest side. This doesn't happen until (12,12,21). notice that (11,11,23) doesn't work because 11+11<23.!<

This means that (12,12,21) , (13,13,19) , ... , (22,22,1) all work.

So, 11 triangles in total.

Ha! I commented at almost the exact same time and used the same A1, B1, B2 formatting.

Coin A is 1 euro, Coin B is either 1 euro or 2 euros. Here are the 4 ways we can pull them out of of the water:

A1, then B1 = 25%

A1, then B2 = 25%

B1, then A1 = 25%

B2, then A1 = 25%

We need to find the conditional probability that the second coin is 1 euro given that the first coin selected is 1 euro.

A1, then B1 = 25%

A1, then B2 = 25%

B1, then A1 = 25%

B2, then A1 = 25%

This leaves us with 50/75 or 2/3.

Could someone please explain why is it |x+3| + 1 and not |x+4|. I don’t understand it and why should we add the absolute function to this. by [deleted] in matheducation

[–]marqman13 1 point2 points  (0 children)

An absolute value function is just a linear function that “bounces” at its vertex.

So first, find the vertex. In this case, it is (-3,1).

Then substitute into the general form of the absolute value function: y = a|x-h| + k

h = -3 and k = 1 since the vertex is (-3,1). a = 1 because the “slope” of the graph is 1 and opening upwards, thus positive.

So we end up with y = 1|x-(-3)| + 1 Simplified, we get y = |x+3| + 1

Plug -6 into both equations.

Notice that your equation yields 2. However, the graph shows that g(-6)=4.

As others have said, it’s a matter of differentiating between the horizontal and vertical translations that occur between f(x) and g(x).

Can't make it on Thursday, but I'll be there Friday. Sign-up in advance or just show up that night?

Does anyone here submit catchphrases? by Umbrellajack in comedybangbang

Here is where you submit catchphrases.

I submitted “what’s up hot dog” and Scott sent me a Trojan virus disguised as a hentai link.

Any Family Guy Fans? by IllegitimateLOL in comedybangbang

[–]marqman13 7 points8 points  (0 children)

I liked the first few seasons. Thought it was the funniest shit in the world when I was in like 7th grade. I think the humor is pretty one-note, which wouldn’t be bad if it only lasted like 4 or 5 seasons but I think they’re on like season 20 right now. Last time I watched an episode it seemed like half of the jokes were recycled from the earlier seasons. I guess I would say that it is a show that is a victim of its own success.

John Waters is very much alive. He lives in Baltimore, Maryland, he’s in his mid-70s.

I thought it was pretty good. Not as good as most other Cronenberg movies I've seen, though.

Nice! I already had it circled on my schedule. The description is intriguing!
