The probability that none of the shoes are black is 51.2%.
If 20% of the shoes are black, then 80% of the shoes are not black. To find the probability that three shoes are not black, we have to multiply 80% by itself 3 times.
0.8 x 0.8 x 0.8 = 0.512 = 51.2%
How far does a wheel move when it rotates once? The length of the outside of the tyre? Isn't that the same as the circumference?
The answer is B cause you multiplied them not add or subtract
The answer is 37.68 because you first find the area of the circle which is pie r^2 or 50.24 then you find the fourth of that which is 12.56 so you subtract 12.56 from 50.24 to get the answer of 37.68
