Question

30. A bag contains 3 red balls, 5 white balls and 8 blue balls. One ball is taken
out of the bag at random. Find the probability that the ball taken out is
(a) a red ball, (b) not a white ball.​

Answer 1

Answer:

Step-by-step explanation-  total number of balls = 5+3+8=16 balls

a)a red ball

 p(a red ball)= no. of red balls/total no. of balls

                      =3/16

b)not a white ball= sum of red and blue balls/total no. of balls

                              = 3+5/16                                              

                              = 8/16

                              = 1/2
