Michelle draws a card from a standard deck of 52 cards. She replaces the card and draws a second card. What is the probability that she draws a heart and then a spade?

[Note: There are 13 each of hearts, spades, clubs, and diamonds.]

Answer 9

hang on I am figuring it out

Answer 10

ok

Answer 11

So first you need to work out the probability of drawing a heart

Answer 12

P(heart and spade) = P(heart) x P(spade)

Answer 13

Okay so you have 52...13 of each kind of card...so 13 multiplied by 2 would be 26...so it would be 26/50 and then you have to simplify it...

Michael has a drawer with 8 pairs of black socks and 12 pairs of white socks. Without looking he takes a white pair of socks out of the drawer. What is the probability that the next pair he takes out is black?

Answer 15

Answer 16

add the 2 numbers together

Answer 17

8+12=?

Answer 18

Answer 19

okay its 20...so it would be 8/20 simplified would be 2/5...

@adelyn_helps that's not quite right. Replacement didn't occur - so only 11 white socks are in the drawer
