Find the probability that the two digit number formed by digits 1… - Vidyadip

MCQ

Find the probability that the two digit number formed by digits $1, 2, 3, 4, 5$ is divisible by $4$ (while repetition of digit is allowed)

A
$\frac{1}{{30}}$
B
$\frac{1}{{20}}$
C
$\frac{1}{{40}}$
✓
None of these

✓

Answer

Correct option: D.

None of these

d
(d) Total number of numbers $ = {(5)^2}$

Favourable cases $= [12, 24, 32, 44, 52]$

$\therefore$ Required probability $ = \frac{5}{{25}} = \frac{1}{5}.$

Statement $I$ : For any two non-zero complex numbers $\mathrm{z}_1, \mathrm{z}_2$

Statement $II$ : If $\mathrm{x}, \mathrm{y}, \mathrm{z}$ are three distinct complex numbers and a, b, c are three positive real numbers such that $\frac{a}{|y-z|}=\frac{b}{|z-x|}=\frac{c}{|x-y|}$, then
