Et y represent the number of students in the group who are not members. You can write an expression for y in terms of x from the information given. What do you know? The total number of students = 19 x + y = 19 which gives you y = 19 - x OR you also know the total cost is 209 and you can use that and the cost of the two types of tickets to obtain an expression for y in terms of x.
Answer:
no, since the numbers are mixed up both negative and positive
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
