<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>

3. 3/4
Step-by-step explanation:
A full strip and a half of staples = 1 strip + 0.5 strips = 1.5 strips
1.5 strips = 315 staples
Divide both sides of the equation by 1.5 to find out how many staples are in one strip:
1.5 strips ÷ 1.5 = 315 staples ÷ 1.5
1 strip = 210 staples
Now halve both sides of the equation to find out how many staples there are in half a strip:
1 strip ÷ 0.5 = 210 staples ÷ 0.5
0.5 strips = 105 staples
Therefore, there are 105 staples in half (0.5) a strip.
