You select a card at random from a standard deck of 52 cards. What is the probability of drawing a… a) a black card? b) a spade? c) a jack? d) a black jack? e) a face card (jack, queen, or king) that is not a heart?

favorable events to draw a black card=26 total=52 P=26/52=?

OpenStudy (rock_mit182):

since there are 13 clubs and 13 spades the probability for a) is: 13/52 + 13 /52 which is equal to: 26/52

OpenStudy (rock_mit182):

you can simplify 26 /52 = 13/26 = 1/13

OpenStudy (anonymous):

type error 1/2 not 1/13

OpenStudy (rock_mit182):

lol my bad, that's right 1/2

OpenStudy (xaze):
