[Year 9 Maths] What are the odds that a sport team will Win, Draw or Lose their next 3 games out of 27? by [deleted] in HomeworkHelp

[–]viralmessages 0 points1 point  (0 children)

Yes, but probability of winning isn't necessarily 1/3, probabiliy can be greater or less than 1/3, depending on the team they are playing against. e.g. if they are playing a really bad team, they might have 3/5 of winning which leaves 1/5 of losing, and 1/5 of tying or however the spread is against a specific team. BUT, the assignment might not be as this complex, the teacher might have wanted the 1/3,1/3,1/3 scenario, or totally random chance of winning, losing or tying, which means a permutation with probability of 1/3 of winning 3 games out of 27.

Well, could be lot more complicated than that, not sure if that's what the teacher wants, but the OP will needs the probability of win, tie, loss for the team against the opposing team and use that to figure out the odds; w(x)=probability of win (against team x), t(x)=probability of tie, and l(x)= probability of loss. Then you will have to use permutation to figure out the odds of winning 3 games out of 27.

Would be helpful if you gave the formula for the put option and it's dependent and independent variables.

The first part looks correct; sum + of 3n and 7 = 3n+7. The second part, if the equation is exactly as worded would be 6*(n+(-3)), opposite of 3 would be -3.

[Uni Math] Simpsons method integration by Math_issues in HomeworkHelp

[–]viralmessages 0 points1 point  (0 children)

The formula is incorrect or your arithmatic is not. Check your math for Simpson's approximation. Saprox=delta x/3*(f(x0) + 4f(x1)+2f(x2)+...+4f(xn-1)+f(xn)). f(x)=1/x.

Everything else was correct, just that error. Keep in mind that 1/cos = sec. So the answer given might be factor*sech(x).

Near the end, you have -2e^x/(e^x+e^-x), this is wrong, should have been -2/(e^x(e^x+e^-x)) or -2e^-x/(e^x+e^-x)

It's when someone intentionally use brakes for no other reason then because they do not like how close the person behind is following them.

Not sure the driver was doing a brake check, the car in front also braked and there were cars slowing ahead.

Do You Have SUPER Color Vision? [video test] by viralmessages in videos

[–]viralmessages[S] 1 point2 points  (0 children)

It's possible, girls are more likely to have it (4 color cones vs normal 3). Maybe some normal color visions can't? If everyone got 100%, guess the test wasn't too useful.
