Question 1115882
use the binomial probability formula
:
Probability (P) (k successes in n trials) = nCk * p^k * (1-p)^(n-k), where nCk = n! / (k! * (n-k)!)
:
for this problem, n=10, k=9, p=0.86
:
P (9 successes in 10 trials) = 10C9 * (0.86)^9 * (1-0.86)^(10-9) =
:
(10!/(9! * (10-9)!) * 0.2573 * 0.14 =
:
10 * 0.2573 *0.14 = 0.3602 approximately 0.36
