Question

The probability of raining on day $1$ is $0.2$ and on day $2$ is $0.3$. The probability of raining on both the days is

• A. $0.2$
• B. $0.1$
• C. $0.06$
• D. $0.25$

Answer 1

The correct option is C $0.06$

The probability of raining on day $1,P\left(A\right)=0.2$
The probability of raining on day $2,P\left(B\right)=0.3$
Raining on both the day is independent of each other,

Hence required probability $=P\left(A\right).P\left(B\right)$
$=0.2\times 0.3$
$=0.06$

Hence, option C.
