Answer:
The answer Is C because after further review I have realized C is the best answer choice
The answer is C. 16/55 because P(Q and R) = P (Q) . P (R) (for independent events Q and R)
So, the prob. is 4/5 * 4/11 = 16/55 = D.
The correct answer is "525613"
Answer: 15 / 56
Step-by-step explanation:
Number of red checkers = 3
Number of black checkers = 5
Total number of checkers = 8
P(black, then red) = 5/8 × 3/7 = 15/56
We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.
