Two cards are drawn from a standard deck of cards.

Part A: If they are drawn with replacement, what is the probability that both cards are 2s?

Part B: If they are drawn without replacement, what is the probability that the first card is a club and the second card is a spade?

Part C: Which of the two scenarios in Part A or Part B represents dependent events? Explain.

 

Thanks in advance to anyone who helps me.

 

B... it's 13/52 and 13/51 correct?

Part A  with replacement  =   4/52 * 4/52  =  16/ 2804   =  1 / 169

 

Part B without replacement  =  13/52  * 13/51   you are correct   FWAS....!!!....just do the math, now!!!

 

The second is dependent......the probability of drawing a spade on the second draw might be either 13/51 or 12/51    depending on what card is drawn first......
