The probability of getting red and blue ball = 7/45
Given:
A bag contains 7 red,5 blue,and 3 green balls
2 balls are picked up random
To find:
What is probability that first is red and second is blue
Solution:
Given a bag contains 7 red, 5 blue and 3 green balls
Total number of balls = 7 + 5 + 3 = 15
Number of red ball = 7 and number of blue balls = 5
As know Probability of event
= No. of favorable outcomes / total No. of comes
The Probability of getting red ball = 7/15
The Probability of getting blue ball = 5/15 = 1/3
Therefore,
the probability of getting red and blue ball = (7/15)(1/3) = 7/45
