Question

One hundred and 50 people were asked whether they like to see comedies or dramas and whether or not I buy popcorn from for the movie out of 90 people that like comedies they bought popcorn day or 40 people that said they do not buy popcorn

Answer 1

Answer: a) 0.6, b)
`(4)/(15)`

Explanation:

Since we have given that

Total number of people were surveyed = 150

Number of people that like comedies they bought popcorn that day = 90

Number of people that said they do not buy popcorn = 40

So, Probability of getting who like comedies and bought popcorn =
`(90)/(150)=(3)/(5)=0.6`

Probability of getting who said they do not buy popcorn =
`(40)/(150)=(4)/(15)`

Hence, a) 0.6, b)
`(4)/(15)`
