well, what is .15 * 20 ?
300
so 15 because 20 is multiplied 15 times?
No, that's 0.15 * 20
Look. 15% means you expect 15 wins in 100 tries.
20 is only 1/5 of 100, so you expect 1/5 as many as 15, or 3.
0.15*20 = 3
That is, 15% of 20 is 3.

i'm really sorry i'm late!
first, multiply the percent by the number of trials:
15 x 20
next, divide it by 100 ,
if it ends up as a decimal, round it up to the nearest whole number. hope this helped you!
