Question

One card is dealt. Find the chance that its color is red or its rank is an even number.

Answer 1

In a deck of 52 cards, 26 are red.
Out of the black cards, there are two different suits with 5 even-numbered cards in each suit, so there are 10 black even cards.
There are 36 cards out of 52 that satisfy your requirement.

36/52 =9/13
You are correct
