Probability is a quantitative measure of the likelihood of the occurence of an event. It is given mathematically as:
[tex]P=\frac{No\text{ of expected outcome}}{Sample\text{ size}}[/tex]Those without interest in taking skiing lesson = 400 - 96 = 304
Sample size = 400
Therefore, Probability is:
[tex]P=\frac{304}{400}=\frac{19}{25}[/tex]
