Answer is 40
15/3 = 5
8 x 5 = 40
No, this is an equation which you are to solve.
Add 12 to both sides of the equation: y = 19+12, or y = 31 (solution).
Problem Page Question An urn contains black and pink balls. Four balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all balls drawn from the urn are pink? Round your answer to three decimal places.
B=1/2
9/16=1/2b(3/4)
Divide both sides by 3/4
1/4=1\2b
Multiply both sides by 2
