4.) In a vaccination facility, there were 10 male and 8 female in attendance. 4
male and 2 female are aged 50 yrs. old and above. What is the probability of
selecting a male or below 50 yrs. Old​


Sagot :

Given:

total number of males in attendance = 10

total number of females in attendance = 8

total number of people in attendance = 18

total number of males aged 50+ = 4

total number of females aged 50+ = 2

total number of males below 50 = 10-4 = 6

Probability of selecting male or below 50:

[tex] \frac{10}{18} + \frac{6}{18} = \frac{8}{9} [/tex]
