Assuming a standard deck of 52 playing cards. Calculate the the probability.
Draw one card thatis a queen and a heart.
is it 4/52 + 13/52 - 1/52 = 16/52 or 4/13
is this right??
Draw one card that is a queen or a heart
4/52 +13/52 - 2/52 =15/52
not sure if I have the right or wrong answer on these two, please help
Thanks

If one card is a queen <I>and</I> a heart, it is the queen of hearts. 1/52
Since the probability of Queen of hearts is 1/52
4/52 + 13/52 - 1/52 = 16/52
Since the probability of Queen of hearts is 1/52
4/52 + 13/52 - 1/52 = 16/52
