14.Probability
easy

$P(A)=\frac{3}{5}$ અને $P(B)=\frac{1}{5}$ આપેલ છે. જો $A$ અને $B$ પરસ્પર નિવારક ઘટનાઓ હોય તો $P(A$ અથવા $B$) શોધો.

Option A
Option B
Option C
Option D

Solution

Here, $P ( A )=\frac{3}{5} $,  $P ( B )=\frac{1}{5}$

For mutually exclusive events $A$ and $B,$

$P ( A $ or $B )= P ( A )+ P ( B )$

$P ( A $ or $B )=\frac{3}{5}+\frac{1}{5}=\frac{4}{5}$
