Question

If a resident who has completed just high school or only some college is chosen at random , what is the probability that they are aged 50 or over ? Round your answer to the nearest thousandth .

Answer 1

Probability of a a resident who has completed just high school or only some college being aged 50 or over = 0.340

Step-by-step explanation

The probability of an event is calculated as the number of elements in the event divided by the total number of elements in the sample space.

For this question,

Number of residents that completed high school or only some college that are aged 50 or over = 1942 + 1057 = 2999

Total Number of residents that completed high school or only some college = 3775 + 5042 = 8817

Probability of a a resident who has completed just high school or only some college being aged 50 or over = (2999/8817) = 0.340

Hope this Helps!!!
