Question

A bag contains x white, y red and z blue balls. A ball is drawn at the random, then what is the probability of drawing a blue ball.

​

Answer 1

The probability of drawing a blue ball

from the bag depends on the total number

of balls in the bag. If you know the total number of balls (x + y + z) and the number

of blue balls (z), you can find the probability by dividing the number of blue balls by

the total number of balls. The formula

for the probability of drawing a blue ball would be \( \frac{z}{x + y + z} \).

Answer 2

Probability of drawinga blue ball = Z/x + y + Z

Explanation:

Given :- A bag contains x white, y red and z blue balls. A ball is drawn at the random.

To Find :- the probability of drawing a blue ball.

Solution :
`\pmb{ \sf{↴}}`

Number of blue balls = Z

Total balls = x + y + Z

•°• P(a blue ball) =
`\pmb{ \sf{(z)/(x + y + z) }}`
