Question

An integer is chosen between 70 and 100. Find the probability that it is
(b) divisible by 7​

Answer 1

Answer:

$\frac{4}{29}$

Step-by-step explanation:

Since, the numbers between 70 and 100 which are divisible by 7,

77, 84, 91, 98,

Also, the total numbers between 70 and 100 = 29,

$\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

Hence,

The probability of a number between 70 and 100 is divisible by 7​

$=\frac{4}{29}$
