Your answer would be 541.5
<span>The answer to this question depends on the class size. However if we assume the class is sufficiently large then we can assume the 65% ratio stays relatively constant as students are selected. In this case we will treat selecting three students as independent events. Therefore we can multiply the probabilities. Finally, the probability of selecting three students that all like statistics more than algebra is (0.65)x(0.65)x(0.65) = 0.275.</span>
Answer:
upper and lower results have to be the same
so set them equal
5x = 2x + 1
subtract 2x on each side
3x = 1
devide each side by 3
x = 1/3
You are welcome
