Question 994074: Ten peas are generated from parents having the green/yellow pair of genes, so there is a .75 probability that an individual pea will have a green pod. Find the probability that among the 10 offspring peas, at least 9 have green pods. Is it unusual to get this result (hint: compare it with the cutoff probability we established for the Rare Event Rule)?
I got 0.244025230.

Binomial Problem with n = 10 and p(green) = 0.75
---
P(9<= x <=10 = 1-P(0<= x <=8) = 1 - binomcdf(10,0.75,8) = 0.2440
