Answer:
1/5
Step-by-step explanation:
Total number of customers = 200
Find the number of people who likes Vanilla:
Like Vanilla = 60% of 200
Like Vanilla = 0.6 x 200
Like Vanilla = 120 people
Find the number of people who does not like Vanilla:
Does not like vanilla = 200 - 120
Does not like vanilla = 80 people
Find the number of people who likes mango flavor:
Like Mango = 80% of 200
Like Mango = 0.8 x 200
Like Mango = 160 people
Find the number of people who does not like mango flavor:
Does not like Mango = 200 - 160
Does not like Mango = 40 people
Find the number of people that like at least one of them:
Like at least one of them = 120 + 160 - 80 - 40
Like at least one of them = 160
Find the number of people that does not like either of them:
Does not like either of them = 200 - 160
Does not like either of them = 40
Find the probability of people who does not like either of them:
P(does not like either of them) = 40/200 = 1/5
Answer : 1/5
