Question

Compute the following binomial probabilities directly from the formula for b(x; n, p).

(a) b(1; 6, 0.43)


(b) b(1; 7, 0.77)


(c) P(3 X 5) when n = 9 and p = 0.69


(d) P(1 X) when n = 9 and p = 0.21

Answer 1

try urself with prob=C(n,x) * (p^x) * (1-p)^(n-x)
for a) it is C(6,1) * (0.43)^1 *(1-0.43)^(6-1)

Answer 2

i hope rest u will be able to do as just u hv to plug in for x,n and p
