Question

A natural number lies between 6 and 32 what is the probability that the number is a multiple of 5

Answer 1

All the multiples of 5 that lie between 6 and 32 are: 10, 15, 20, 25, 30 (i.e. 5 numbers)

P(event) = $\frac{Number Of Favourable Outcomes}{Total Number Of Outcomes}$

Total number of outcomes = (31-7) + 1

= 24 + 1 = 25

P(multiple of 5) = $\frac{5}{25}$ = $\frac{1}{5}$
