Explanation / Answer

Que.48. Find the probability of the event randomly choosing a resident who is not 45 to 59 years old.

Solution:

The data about the age distribution of resident of San Ysidro, New mexico, is given.

We have to determine the probability for the specified event.

The sum of the frequency is 38 + 20 + 31 + 53 + 36 + 15 = n(S) = 193

Event B: randomly choosing a resident who is not 45 to 59 years old = 193 - 53 = 140

P( Not 45 to 59 years old) = n(B) / n(S) = 140/193 = 0.73
