I need help with a quick question. I will medal the person with the best answer. Thanks! Find the probability of drawing a heart or a black card from a standard deck of cards. 8/13 0 ¾ 19/26 I don't know this because I have never played with face cards. Help please.

Don't worry, this isn't very hard.

OpenStudy (anonymous):

There are 13 cards of each suit, with four suits. There are a total of 52 cards.

OpenStudy (anonymous):

2 suits are black, 2 suits are red.

OpenStudy (anonymous):

there are 26 black cards. there are 13 hearts.

OpenStudy (anonymous):

So we have 52 / 26 + 13

OpenStudy (anonymous):

52 / 39

OpenStudy (anonymous):

wait, it's 39 / 52.

OpenStudy (anonymous):

which is 0.75.

OpenStudy (anonymous):

or 3/4.

OpenStudy (anonymous):

So the answer is C. \[\frac{ 3 }{ 4 }\]
