d
Step-by-step explanation:
P(A and B) = P(A) x P(B)
0.6 = 0.8 x P(B)
0.6/0.8 = P(B)
P(B) = 0.75
The slope of machine 1 is 0.3. And machine 2 is 3/8. Hope this helped

Since Max's deck of cards contains the same number of blue cards as Barry's,
letting x as the number of red cards in Max's deck of card
40 / x = 8 / 9
Solving for x
360 = 8x
x = 45
There are a total of 40 + 45 = 85 cards in Barry's deck of cards
