MCQ
The probability that a number selected at random from the numbers $\{1, 2, 3, ..., 15\}$ is a multiple of $4,$ is
- A$\frac{4}{15}$
- B$\frac{2}{15}$
- ✓$\frac{1}{5}$
- D$\frac{1}{3}$
✓
Answer
Correct option: C.
$\frac{1}{5}$
Total No. $= 15$
No. of multiples of $4$ between $1$ and $15 = 3$
$P($a number selected from the number $\{1, 2, 3, .... 15\}$ is a multiple of $4)$
$=\frac{3}{15}$
$=\frac{1}{5}$
No. of multiples of $4$ between $1$ and $15 = 3$
$P($a number selected from the number $\{1, 2, 3, .... 15\}$ is a multiple of $4)$
$=\frac{3}{15}$
$=\frac{1}{5}$
