Question

Himanshu draws a ball from a bag that contains 10 white balls and 20 yellow balls.Find the probability of choosing a white ball.

Answer 1

Answer:

1/2

Step-by-step explanation:

total balls is 30, white balls are 10 and P(E)=no.of white balls upon total no. of balls. 10/30=1/3

Answer 2

The probability of choosing a white ball by Himanshu is 1/3

Solution:

It is given that there are 10 white balls and 20 yellow balls. So the total number of balls is 30. Now it is said that Himanshu picks 1 ball from the total number of balls

We have to find out what is the probability that the ball he picked is white.

The probability that the ball he picked is white $=\frac{\text { Number of white balls }}{\text { Total Balls }}$

$\frac{10}{30} = \frac{1}{3}$

The probability of choosing a white ball by Himanshu is $\frac{1}{3}$
