Question

In a showroom, there are $100$ cars. $10$ cars are black, $20$ cars are red, $15$ cars are blue, $25$ are white and $30$ are grey.

A car is chosen at random, what is the probability that it is a white car?

• A. $1$
• B. $\frac{1}{2}$
  
• C. $\frac{1}{3}$
  
• D. $\frac{1}{4}$
  

Answer 1

The correct option is D $\frac{1}{4}$


Given:
$\bullet$ Number of white cars $=25$
$\bullet$ Total number of cars $=100$

The probability $\text{P(W)}$ that a car is of white color is:

Number of favorable outcomes $=$ Number of white cars $=25$

Total number of outcomes $=$ Total number of cars $=100$

$\text{P(W)}=\frac{\text{Number of white cars}}{\text{Total number of cars}}$

$\text{P(W)}=\frac{25}{100}$

$\text{P(W)}=\frac{1}{4}$


The probability of chosing a white car is $\frac{1}{4}$.

Therefore, option (d.) is the correct answer.
