Question

Jennifer chooses a playing card at random from a deck of 52 cards then she chooses another one. What is the probability that she will get 2 cards that are hearts?

Answer 1

There is a
`(13)/(52)` chance she will pick a heart the first time and a
`(12)/(51)` that she will the second time.
The probability of this occurring thus is:

`(13)/(52)* (12)/(51) = (13*2*2*3)/(2*2*13*3*17)`

`= (1)/(17)`

Answer 2

52 cards in a deck
4 suits
1/4 of 52 are hearts
1/4 of 52=13 cards

probability of getting 1 heart at first is 1/4

one card is taken out and assuming that it is the heart, 13-1=12,52-1=51
12/51

multiply
1/4 times 12/51=3/51=1/17
