This is a binomial distribution.
p = 0.71, q = 1 - p = 1 - 0.71 = 0.29, n = 20
P(x ≤ 19) =1 - P(x = 20) = 1- 20C20 x (0.71)^(20 - 20) x (0.29)^20 = 1 - 0.29^20 = 1 - 0 = 1
The ratio of free throws to miss throws = 4/3
Miss throws = 36
So, free throws would be = 36 * 4/3 = 48
So, your final answer is 48
Hope this helps!
I would say go with with B
The answer is 15.25 cubic inches
you multiply 35 to 72 to get 2520 and then multiply 23 to 94=2139 add both of the answers to get 4659
