Question

a survey indicates that 41% of women in the us consider reading as their favorite leisure time activity. you randomly select 4 women and ask them if reading is their favorite leisure time activity. find the probability that exactly 2 of them said yes

Answer 1

The easiest way to do this problem is to use a binomial probability table. If you use the table, n = 4, x = 2, and p = .41

Answer 2

100-41=59
41% Yes
59% No

4 C 2 = 6 (possible combos)

6(.41)^2*(.59)^4=.122216
