Question

There are 7 red cards, and 13 blue cards in a deck of cards. If Yuki randomly selects a card from the deck, what is the probability that it is a red card?

Answer 1

7+13=20

7/20=35/100

so there is a 35% chance of it being a red card

Answer 2

Answer: 7/20 or 35%

Step-by-step explanation: You add up all of the cards she has and then you put that number on the denominator. Next you put how many red cards she has on the numerator. Lastly, you see if you can simplify, but in this case it already is simplified. If you need it to be a percent then you simply divide the numerator by the denominator. 7/20= 0.35. Then you move the decimal point 2 places to the right. Your percent is 35%.
