Answer:
Step-by-step explanation:
What is the probability that when two cards are drawn from a deck of cards without
replacement that both of them will be 8’s?
(ℎ 8
′
) = ( 8) ∙ ( 8)
( 8) =
4
52
There are three 8’s left in the deck if one is pulled and not replaced, and 51 total
cards remaining.
( 8) =
3
51
(ℎ 8
′
) =
4
52 ∙
3
51 =
12
2652 =
1
221 = .0045 .45%
First make the denominators the same = 4 5/20 - 3 12/20. Then make them improper fractions= 85/20-72/20= 13/20. Since that is already simplified the answer is 13/20.
Answer:
I don’t know 160.
