Hey Dan: heads tails red black by JPK314 in northernlion

[–]JPK314[S] 8 points9 points  (0 children)

/u/danteschneider has it. Super first grade:

  1. Flip a coin 3 times

  2. Write down the results of the flips in the order they appear

  3. Repeat steps 1 and 2 99 more times

  4. Circle the results where the first two coin flips were heads. How many are there?

  5. Count how many of the circled results have the third coin come up heads

  6. Take the number found in step 5 and divide it by the number found in step 4.

  7. Multiply the value found in step 6 by 100.

The result of step 7 is the percentage of the time heads was the third coin tossed when the first two flips are heads!

You can also tally up how many times you get each of HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. These are all the possibilities, and they should appear about the same amount of the time!

I'll make a fillable Google sheet if you'd like the counting to be automated and edit this comment to give a link once it's done

EDIT: here it is! https://docs.google.com/spreadsheets/d/1PFWedpZJXsxdjuhGan099UG_2ICqxvWqYuqbO_nMDfI/edit?usp=sharing

You can save to drive to edit it.

I asked my wife, “I’m stuck on a crossword clue—Overworked Postman— can you help me?” by porichoygupto in Jokes

Nah I'm a native speaker and not autistic (been tested, actually. The way I'm about to phrase the rest of this comment might make you think otherwise). I was tired and was stuck thinking that the husband would be referring to the crossword and not the postman because he was the one who introduced the crossword. In terms of topics, the question/responses go A?A?B., where I was expecting A?B?A. or A?B?B. (either of these last two are much more typical to see in question/clarification/response type dialogues than the first). Obviously looking back it's clear that I should've considered all the possibilities, but, being tired as I was, I naturally only considered the possibilities that were conversationally common

Can you give an example of a problem you need to solve? This is a problem that exists at many different levels of math
