Question

P (two of hearts0 I got 1/52 correct
P ( two)I got 4/52 correct 
P  (heart)I am not sure.

Steve · Answer

you are correct on the first two. The last should also be no sweat.

There is only 1 2-hearts in the deck of 52

There are 4 twos in the deck.

So, how many hearts are there?

Also, just as advice, usually you will need to reduce your fractions for your final answers. 4/52 = 1/13

So, revisiting #2 and #3, there are 13 different numeric values, so getting a two has a 1/13 chance.

So, how many suits are there? Each is equally likely.
