If 2 cards are drawn at random from a standard deck of cards with no replacement, find the probability that both cards are heart
I had 13/52 multiplied by 12/51 to get an answer of 1/17

A bucket contains 4 red, 2 yellow, and 3 green balls. If one ball is taken at random what is the probability that is is red or green
I had 4/9 times 3/9 which equals 4/27 as my answer

I just need someone to make sure these are correct

I agree with your first answer.

Since there is only one draw in your second question, and 7/9 of the balls are red OR green, it seems toi me that is the answer.
