Ok so a spade is a 1/4 of the deck correct?
OpenStudy (anonymous):
Actually I can't help sorry gotta go
OpenStudy (anonymous):
If 1/4 of the deck are spades, and 1/2 of the deck is red . . .would it be a 3 outta 4 chance?
OpenStudy (raden):
P(spades or red cards) = P(spades) + P(red cards) = 1/4 + 1/2 = 3/4 so, you are right !
