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.
-4g + 12 = 16 then -12 on the both side
-4g = 4 then divided by -4, you will get g = -1
Answer:
Step-by-step explanation:
9:x = x :4
Product of mean = product of extremes
x *x = 9*4
x² = 36
x² = 6²
x = 6
