A bag contains 5 white balls and 7 red balls. One ball is drawn at random. What is the probability that the ball drawn is white?
Answers
SOLUTION :
GIVEN : Number of red balls = 7
Number of white balls = 5
Total number of balls in a bag = 7 + 5 = 12
Total number of outcomes = 12
Let E = Event of selecting that a ball drawn is white
Number of outcome favourable to E = 5
Probability (E) = Number of favourable outcomes / Total number of outcomes
P(E) = 5/12
Hence, the required probability of getting a white ball , P(E) = 5/12 .
