Question
From a bag of 3 red and 5 blue balls, a ball is drawn randomly. The probability of getting blue is
Hint:
Probability of an event = Number of favourable outcome / Total number of outcomes
The correct answer is:
Here, there are 3 red balls and 5 blue balls in a bag. We have to find the probability of getting a blue balls.
Total number of outcomes = Number of red balls + Number of blue balls
= 3 + 5
= 8
Number of favourable outcomes = Number of blue balls = 5
Therefore, P ( getting a blue ball) = 5/8
Hence, the correct option is (c).
0 ≤ P(E) ≤ 1.Also sum of probability of all events is 1 i.e Here, P(red) + P(blue) = 1
