Hi
Binomial Distribution:
TI syntax for P(x-value) is binompdf(n, p, x-value).
 white-black in the ratio of 8:5 ...p(W) = 8/13  and q(B) = 5/13
9 off spring
a) P(x = 5W) = binompdf(9, 8/13, 5) = .2433
b) 'expected number' of black rats from part a)  (5/13) * 9 = 3.4615  0r 3
Wish You the Best in your Studies.
