Cards of Deck

Question

One card is drawn from a standard 52 card deck. Find the probability that it is a 7 or a Jack if drawing is done with replacement.

Answer 1

Okay, first, "with replacement" doesn't matter at all if you're only drawing one card.

 

Second, how many 7s are there in the 52-card deck, and how many jacks?  Add those two numbers.   Hint - there's one jack for each suit, and one 7 for each suit. 

 

Put the sum of those two numbers over 52, and that's your probability.
