Question

a recent survey showed that 79 adults out of a sample of 400 do not like cold weather. However, 96 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/she has no desire to take skiing lessons? express your answer as a fraction

Answer 1

Probability is a quantitative measure of the likelihood of the occurence of an event. It is given mathematically as:

`P=\frac{No\text{ of expected outcome}}{Sample\text{ size}}`

Those without interest in taking skiing lesson = 400 - 96 = 304

Sample size = 400

Therefore, Probability is:

`P=(304)/(400)=(19)/(25)`
