Question

A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independent trials of the experiment.

N=9, p=0.9, x=6

Answer 1

0.044

Explanation:

n=9,p=0.9, x =6.

Apply Binomial probability we get

Sum P(x)=C(n,x)
`p^(x) (1-p)^(n-x)` for x=6

Putting in the formula ,

we get

P(x) = C(9,6)
`0.9^(6) 0.1^(3)`

84 X 0.531441 X 0.001

= 0.044
