What is the probability that a card drawn from a standard 52 card deck is a diamond or a three?

6.5%

Step-by-step explanation:

There are 4, number three cards and 4 diamond cards in a deck of 52 cards. Divide 52 by 8.

30.8% or 4/13

Step-by-step explanation:

There are 52 cards in a deck of cards.

There are 4 nines (4/52) and 13 (13/52) diamonds in a deck of cards.

When you add them together, you get 17/52. Then, you have to subtract the card that is both a nine and in a diamond suite, so you subtract -1 because there is only one card that fits both categories. You should have 16/52, which simplifies to 4/13 / 30.8%.

it is x equals 3   plese mark me really need it
