you take 3.9 cubic feet and multiply it by 12 to convert it into inches and you get 46.8 cubic inches. then you divide by 60 to convert minutes to second and you get 0.78. hope that helps
Given that the player made 184 out of 329 throws, the probability of making the next throw will be: P(x)=[Number of shots made]/[Total number of throws] =184/329 =0.559 Thus the expected value of proposition will be: 0.599*24+0.559*12 =20.134
