I am going to take my chances and answer this in the morning if nobody else does. I have some bad phys. ed. memories that I don't want to become nightmares.πŸ˜€ Good night everyone.

  • The chances of Jancgarlest getting points is J: 0.45
  • Chrisrice not getting the point is C: 1.00-0.18 = 0.82...
  • Chances of both events happening is the product of J & C: 0.82*0.45 = 0.369

The chances of Jan scoring but not Chris after they both throw is %36.9

Forgot about the time. Someone else already gave the correct answer of 36.9% but I'll show it my way.
Let X = P(A and Not B) be the probability of Jan and not Chris
Let P(A) = Probability of Jan = 0.45
Let P(B) = Probability of Chris = 0.18

  1. P(A AND B) = (0.18)(0.45) = 0.081
  2. X = P(A) - P(A AND B) = 0.45 - 0.081= 0.369 = 36.9%

Hmmm... I never thought of solving it this way. Thanks for showing this other method.

Answer for Day 6 Math Problem

36.9% 🎯

@chrisrice@jancharlest
Chance to shoot ball18%45%
Chance not to shoot ball82%55%

The problem is basically the chance of @jancharlest shooting the ball multiplied by the chance of @chrisrice not shooting the ball. The solution is 82% multiplied by 45% (or 0.45), whose result is 36.9%.

Winner: @ahmadmangazap πŸ…

I don't know how the percent (%) symbol is written in @ahmadmangazap's country, but his answer is clear.

Did I write it %36.9 again?... It seems I did.

It's written like that in Arabic. (The symbol % is after the numbers in a RTL language.) Since I mentally read the numbers in Arabic even when I'm thinking in English I tend to mix this up.
