Question

If you think of a number from the first 28 natural numbers, what is the probability that the number will be divisible by 6?

• A. $\frac{1}{5}$
• B. $\frac{1}{6}$
• C. $\frac{1}{4}$
• D. $\frac{1}{7}$

Answer 1

The correct option is D $\frac{1}{7}$

Numbers divisible by 6 out of first 28 natural numbers = {6, 12, 18, 24}

Probability
$=\frac{\text{favourable number of outcomes}}{\text{Total number of outcomes}}$
$=\frac{4}{28}$
$=\frac{1}{7}$

Option (d) is the correct answer.
