Brown Eyes If six people are randomly selected, find the probability that none of them has brown eyes.

Step-by-Step Solution:

Step 1:

Given that, if six people are randomly selected, to find the probability that none of them has brown eyes.

Assume that 40% of the population has brown eyes.

Here,  P = 40% = 0.4, q = 1 - p = 1 - 0.4 = 0.6.

Here ‘x’ follows binomial distribution with sample size “n” and proportion “p”.

i.e,   X Probability mass function of binomial distribution is given by

P(x)...
