C i believe, hope it helps
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
Her brother is 28 bc u add on 3 years to Mary so 14 and times that by 2 to get 28
Y=3x-14
y-intercept=-14
x intercept=14/3 or 4 and 2/3
