Question

Can someone help I need this asap

Answer 1

Answer:

Step-by-step explanation:

Total number of students =100

Number who bought pop corn = 62

Number who bought drinks = 47

Number who bought both =38

Hence number who did not purchase anything = 100-(62+47-38)

=29

Prob that students buys a drink = 47/100 = 0.47

PROB THAT THE  student buys a drink/he purchsaed pop corn

= Number for both/number of pop corn

=38/62 =0.613

P(buying pop corn) = 0.62 and P(drink) = 0.47

Product of these = 0.62*0.37=0.2356

Thus we find product is not equal to Prob of purchsing both

Hence cannot be independent
