An Ice-cream cafe has 200 customers every day. 60% of them like vanilla flavor and 80% of them like mango flavor. What is the probability, if one of the customers selected randomly and asked which flavor does he/she likes and they don’t like either of them.
Answers
8% is the probability they don’t like either of them
Step-by-step explanation:
An Ice-cream cafe has 200 customers every day. 60% of them like vanilla flavor and 80% of them like mango flavor.
Probability of liking Vanilla flavour = 0.6
Probability of not liking Vanilla flavour = 0.4
Probability of liking Mango flavour = 0.8
Probability of not liking Mango flavour = 0.2
Probability of not liking any flavour = (0.4)(0.2)
= 0.08
= 8 %
8% is the probability they don’t like either of them.

The probability of randomly selecting when they don't like either of them is 8%
Step-by-step explanation:
Probability of liking vanilla flavor = 60%
Probability of not liking vanilla flavor = 1 - 60% = 40%
Probability of liking mango flavor = 80%
Probability of liking not mango flavor = 1 - 80% = 20%
The probability of randomly selecting the not liking flavor:
P = 40% × 20%
P = 40/100 × 20/100
P = 0.4 × 0.2
∴ P = 0.08 × 100 = 8%
