7/8 you have to make 1/4 into 2/8 and 2/8+5/8=7/8
Let
L=event that a selected worker has low risk
H=event that a selected worker has high risk
We need to find
P(HL)+P(LH)
=5*20/(25*24)+20*5/(25*24)
=1/6+1/6
=1/3
The 4 curved white corners = 1/4 of whole circle with radius 1/2×6
total white area = 4 [1/4 (pi)(3)^2] = 9pi = 28.27
So the shaded green region (S) = total square - total white area
S = 6×6 - 28.27 = 36 - 28.27 = 7.73 sq. m
