Suppose that left-handedness is independent of possession of a Visa card. Suppose that the probability that...
Homework Answers
Let , A be the event that the person is left-handed and B be the event that the person possesses a Visa card.
Given that P(A)=0.10 and P(B)=0.60
Since , the event A and B are independent.
By definition of independence of event , 
Now we want to find the probability that a person possesses a Visa card or that they are left-handed.
By using the addition rule ,
Add Answer to:
Suppose that left-handedness is independent of possession of a Visa
card. Suppose that the probability that...

a) Among University students it is known that 24% of students have a Visa card, 32% have a Master card and 12% of student have both cards. (1) What proportion of students has a Visa or a Master card? (2) What proportion of students have only Visa or only Master card? b) Suppose that A and B are two events with P(A) =.4 and P(A∪B) = .7. (3) For what values of P(B) would A and B be mutually exclusive?...

Suppose you analyzed the average monthly credit card bill of Visa credit card customers using two randomly selected samples: one with 144 Visa credit card customers (Sample #1) and one with 100 Visa credit card customers (Sample #2). Every credit card customer in Sample #1 had a monthly credit card bill of $1,812. Sample #2, on the other hand, had an average monthly credit card bill of $1,868 with a variance of 1,302,388 ($)^2. If you combined these samples into...
