Question

A sample of 400 adults found that 75 do not like cold weather. However, 92 of those studied said that they had interest in taking skiing lessons. Based on this sample, if an adult is chosen at random, what is the probability that he or she has no desire to take skiing lessons? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.

Answer 1

0.77 or 77/100

Explanation:

The total number of adults in the sample is 400. Out of these, 92 adults expressed an interest in taking skiing lessons. Therefore, the number of adults who do not want to take skiing lessons is 400 - 92 = 308.

The probability of an event is calculated as the number of ways the event can occur divided by the total number of outcomes. In this case, the event is an adult not wanting to take skiing lessons, and the total number of outcomes is the total number of adults.

So, the probability that a randomly chosen adult does not want to take skiing lessons is 308/400 = 0.77 (rounded to the nearest millionth)
