Given that,
Number of red balls are 3
Number of white balls are 5
Number of blue balls are 8.
To find,
The probability that the ball taken out is (a) a red ball, (b) not a white ball.
Solution,
Total number of balls are 3+5+8 = 16 balls
Probability of an event E is given by :
(a) For a red ball,
Favourable outcomes = 3
(b) For not a white ball,
Favourable outcomes = no of red balls + no of blue
= 3+8
=11
Hence, this is the required solution.
