2. 2 clubs

3. an ace and then a 2

4.neither is a diamond

5.A black 10 and then a red ten

Without replacement:

6.2 Queens I know this 1.. Its 4/52*3/51

7.2 clubs

8.an ace and then a 2

9.neither is a diamond

10.A black 10 and then a red ten

Please just give me the first part. I will figure out the rest. Because I don't play cards but I really need help on this or I will fail math. Thank you very much:)

There are 13 clubs in a deck. Since there is replacement, the events are independent.

(13/52)(13/52)


3. an ace and then a 2

There are 4 Aces and 4 twos. (4/52)(4/52)


4.neither is a diamond
