Step-by-step explanation:
i)Probability of getting white or blue ball
=total number of favorable outcomes/total number of outcomes
hence, total number of outcomes= total number of balls
=5+7+4+2
=18
total number of favorable outcomes=5+2
=7
hence, probability=18/7
ii) Probability of getting a red or blue ball
=total number of favorable outcomes/total number of outcomes
total number of outcomes=18
total number of favorable outcomes=7+4
=11
hence, probability=11/18
iii)Probability of not getting white ball
=total number of favorable outcomes/total number of outcomes
total number of outcomes=18
total number of favorable outcomes=18-5
=13
hence, probability=5/18
iv)Probability of getting neither white nor black ball
=total number of outcomes/total number of favorable outcomes
total number of outcomes=18
total number of favorable outcomes. = 18-(5+4)
=18-9
=9
hence, probability=9/18
=1/2.
