21,515754×48 >>> 38%+10% =48%
21,515,754×48= 1032756192 estimates to D.
Answer:
((4 choose 3)·(48 choose 2) + (4 choose 4)·(48 choose 1)) / (52 choose 5) = 19/10829 = 0.0018
Given the slope m and a point (a,b) of a line, its equation is given by

In your case, a = -4, b = 7 and m=1/2, so we have

22% since 100-78 is 22 so that is the percentage of numbers between 78 and 100
