Question

There were 10 green bottles sitting on a wall. The probability of of a green bottle accidently falling is 0.95. What is the probability that fewer than 6 of the green bottles accidently fall

Answer 1

Explanation:

This is a Binomial distribution

Probability of r happening from n trials =

P (X = r) = nCr × pʳ × (1-p)^n-r

So we calculate the P values from r = 1 to 5 with n = 10 and p = 0.95 and add them: - we get 0.0000637 which we can write as 0.006%
