1) A basket has 2 red balls and 2 blue balls. If two balls are drawn successively at random (i.e. without replacement and order mattering), what is the probability of getting a red ball followed by a blue ball?

a) 1/2

b) 1/5

c) 1/3

d) 1/4

2)

Suppose a card is drawn from a standard deck of 52 cards. Let A be the event that a king selected, and B be the event that a heart is selected. What is the conditional probability P(B|A)? Note: It may be easier for you to do calculation by hand instead of using an R! Keep in mind that there are 4 kings in the deck and 13 hearts in the deck. One of the 4 kings is a heart.

a) 1/2

b) 1/52

c) 1/13

d) 1/4
