Question

A box contains four green, five white and seven blue balls. A ball is chosen at random. Find the probability that the ball chosen is green

Answer 1

The probability that the ball chosen is green is 0.25.

Step-by-step explanation:

We are given that a box contains four green, five white and seven blue balls.

A ball is chosen at random and we have to find the probability that the ball chosen is green.

As we know that; Probability of an event  =  $\frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}$

Also, the value of Probability lies between 0 and 1.

Number of green balls in box = 4

Number of white balls in box = 5

Number of blue balls in box = 7

Total number of balls in box = 4 + 5 + 7 = 16

Now, probability that the ball chosen is green =  $\frac{\text {Number of green balls in box}}{\text{Total number of balls in box}}$

                                                                               =  $\frac{4}{16}$

                                                                               =  0.25

Therefore, the required probability is 0.25.
