Answers
Given : An estimated 40% of all the people were born after the year 2000. two people are selected at random from around the world,
To Find : chances that NEITHER of these people were born after the year 2000
Solution:
Mean p = 0.4 ( 40 %)
q = 1 - p = 1 - 0.4 = 0.6
n = 2
x = 0
p(x) = ⁿCₓpˣqⁿ⁻ˣ
p(0) = ²C₀(0.4)⁰(0.6)² = 0.36
chances that NEITHER of these people were born after the year 2000
= 0.36 or 36 %
