SOLUTION: A standard deck of cards has 52 cards. One card is selected from the deck a) compute the probability of randomly selecting a four or eight b) compute the probability of r

Question 1067902: A standard deck of cards has 52 cards. One card is selected from the deck
a) compute the probability of randomly selecting a four or eight
b) compute the probability of randomly selecting a four or eight or six
c) computer the probability of randomly selecting a three or heart
a) P(four or eight)=
b) P(four or eight or six)=
c) P(three or heart)=

Answer by math_helper(2461) (Show Source): You can put this solution on YOUR website!
a) There are four 4's and four 8's:
P{4 or 8} = (4+4)/52 = 8/52 =

b) There are four of each card rank: 4, 8, and 6:
P{4, 8, or 6} = (4+4+4)/52 = 12/52 =
c) There are four 3's and 13 hearts. However, we are counting 3 of hearts in the four 3's AND again when with the 13 hearts, so subtract one to adjust for this double counting (another way to look at it: there are 12 'other' hearts besides the 3 of hearts):
P{3 or heart} = (4 + 13 - 1)/52 = 16/52 =
