Question

In a sample of 30 cats from a population with a probability of 0.19 of having a coat of fur with only one color we want to determine what is the probability of choosing EXACTLY TEN cats whose coat is monocolor.

Answer 1

0.0272

Explanation:

p = 0.19 q = 1 - 0.19 = 0.81

30C10 × p¹⁰ × q²⁰

= 0.02722756555

= 0.0272 (3 sf)
