Question 1149544
<br>
Your presentation of the problem SUGGESTS that the deck of 20 cards consists of 4 cards each with the numbers 1, 2, 3, 4, and 5; but you don't make that clear.  However, a deck like that would produce what you are being told are the correct answers to the problem.<br>
Then the correct use of your formula P(A)*P(B) will give you those answers.<br>
You want the probabilities that each card drawn is NOT either a 3 or a 5.<br>
With replacement, P(A) and P(B) are both 12/20 = 3/5.<br>
Without replacement, P(A) is 12/20 = 3/5 and P(B) is 11/19.<br>
Use those probabilities to get the given correct answers.<br>
