   Three cards are drawn from a standard 52-card deck of cards without replacement. What's the probability that the third card drawn is a heart if the first two cards were also hearts?         A. 11⁄51   B. 26⁄52   C. 13⁄52   D. 11⁄52 In the city of Savannah, Georgia, 22% of young couples take wedding pictures along the Riverwalk (R), and 42% of young couples take wedding pictures in one of the many historical squares (S) throughout the city. However, only 14% of young couples take wedding pictures along the Riverwalk and in the squares. Are these two events independent of each other? Include the reason why or why not.         A. The events aren't independent, because P(R) × P(S) ≠ P(P and S).   B. The events are independent, because P(R) × P(S) ≠ P(P and S).   C. The events aren't independent, because P(R) × P(S) = P(P and S).   D. The events are independent, because P(R) × P(S) = P(P and S)

Quantative Reasoning
 

Banks have charged debit card fees of 44 cents for each transaction, on average. teh federal reserve in june 2015 agreed to cut the fees to a maximum of 24 cents. This cut was a savings for consumers but a loss of revenue banks. The new limit is expected to cost the banks about $6.6 billion in revenue a year. Use the savings per transaction above to calculate the number of debit card transactions in a year.

part a : write an explicit formula that can be used to find the amount of money saved on any given day
