From a well- stuffed deck of playing cards is drawn. Find the probability that:
a.) it is a spade?
b.) it is a face card?
c.) it is a jack?
a) how many spades ? --- 13
so prob = 13/52 = 1/4 (1/4 of the cards are spades, right ?)
b) how many face cards? are aces considered face cards or do we only look at J, Q, K ?
You decide.
c) how many jacks?
prob(jack) = 4/52 = 1/13
