Answer: 0.6

Step-by-step explanation: you add the total amount of cards she has which is 20(6+7+5+2) then the amount of hearts or diamonds is 7+5 for hearts and diamonds, which is =12 so the amount of hearts and diamonds divided by the total amount of cards, 12/20 which is 6/10 when divided by 2, 6/10 is 0.6, if you want to go further 6/10 can be broken down to 3/5 which is also 0.6

Answer:

12/20 = 0.6

Explanation:

The total number of cards in Kayla's hand is:

6 (spades) + 7 (hearts) + 5 (diamonds) + 2 (clubs) = 20

The number of red cards (hearts or diamonds) in Kayla's hand is:

7 (hearts) + 5 (diamonds) = 12

Therefore, the probability of randomly selecting a red card from Kayla's hand is:

12/20 = 0.6
