Question

You have a spinning wheel with $3$ green sectors, $1$ blue sector and $1$ red sector, if the probability of getting a non-blue sector is $\frac{4}{m}$. Then, the value of $m$ is

• A. $5$
• B. $4$
• C. $3$
• D. $1$

Answer 1

The correct option is A $5$

Out of 5 sectors, the pointer can stop at any of the sectors in $5$ ways.

$\therefore$ Total number of outcomes = $5$
There are $4$ non-blue sectors in the spinning wheel, out of which one can be obtained in $4$ ways.

So, the required probability = $\frac{4}{5}$
Hence, the value of $m$ is $5$.
