If a coat is regularly $125, and they mark it down to $75, we could figure out how much money was taken off by subtracting $75, from $125
$125 - $75 = $50
So the coats price was cut by $50.
Hope it helps

Answer:
a.) Expected value on earning points= 21
b.) Expected value on earnings for composites = -1
Step-by-step explanation:
Expected value = [(6*1 + 6*2 + 6*3 + 6*4 + 6*5 + 6*6 ) ]* (1/6) = 6*(7)/2 = 21
b.) how many composite numbers from 1 to 6
4 and 6
so...
Expected Value of earning = [(-6*1 - 6*2 - 6*3 + 6*4 - 6*5 + 6*6 ) ]* (1/6) =
-1 - 2 - 3 + 4 - 5 + 6 = -1
