Question

Find the probability of that a number selected randomly from the numbers $1,2,3,\mathrm{4....}34,35$ is a multiple of $7$.

• A. $1$
• B. $\frac{1}{7}$
• C. $\frac{5}{7}$
• D. $7$

Answer 1

Answer: (B)

$\frac{1}{7}$

Numbers that are multiple of 7 are 7, 14, 21, 28, 35
so P(getting a multiple of 7)= 5/35 = 1/7
