Just do 27/39 to find how much 27 is of 39, and then subtract that from 100 to get the percentage of discount.
27/39 is about 0.69
So the rate of discount is about 0.31
Hope this helps!
Formula for geometric series
an=a1(r)^n-1
a2=1/4(1/3)^1
a2=1/12
The probability from 1.5 ≤ x ≤ 3 can be calculated by dividing the Area from x=1.5 to x=3 by the total Area of the distribution.
The given distribution is rectangular shaped, so its Area will be = Length x Width = 1 x 3 = 3 square units
From x = 1.5 to x = 3, the length is 1.5 and width is 1. So the area between these two intervals = 1.5 square units.
Thus, <span>P(1.5 ≤ X ≤ 3) = 1.5/3 = 0.5
