Answer:
.26%
Explanation:
There are 52 cards in a deck and 13 of them are hears
P (1st card a heart) = 13/52 = 1/4
Then assuming we keep the card
There are now 51 cards with 12 of them hearts
P (2nd card a heart) = 12/51
Then assuming we keep the card
There are now 50 cards with 11 of them hearts
P (3rd card a heart) = 11/50
Then assuming we keep the card
There are now 49 cards with 10 of them hearts
P (4th card a heart) = 10/49
To get the probability the first 4 cards are hearts
P(1st 4 cards are hearts) = P (1st card a heart) * P (2nd card a heart) * P (3rd card a heart) *P (4th card a heart)
= 1/4 * 12/51 * 11/50 * 10/49
=11/4165
=.002641056
Changing to percent by multiplying by 100
=.26%
