Question

Use the frequency table. Find the probability that a person goes to the movies at least 5 times a month. Round to the nearest thousandth.

Answer 1

0.407

Explanation:

To get "probability that a person goes to the movies at least 5 times a month", we need to find total moviegoers that goes to movies EQUAL TO OR GREATER THAN 5 (since atleast) and divide by total moviegoers.

We will add 163 and 133 because they are people who go 5 or greater times.

Total moviegoers is equal to 728 (given).

Thus we have:

`p(\geq5)=(133+163)/(728)\\p(\geq5)=(296)/(728)\\p(\geq5)=0.4066`

Rounding to nearest thousandth, it is 0.407
