Answer:
Step-by-step explanation:
50 employees make up the sales team, 25 male and 25 female, 5 choice leads are assigned
a)
p(first lead given to male)=25/50
p(second lead given to male)=24/49
Since the probabilities of first and second are not affected by each other, the events are independent
b)
Given that first four leads go to men
Therefore, number of men left=21
number of employees left=46
p(fifth lead goes to man)=21/46
c)
At least four leads go to man, given
four leads are men
number of men left = 21
number of women left= 25
number of employes left = 46
probability=

Answer: the shaded region = 69.66mm^2
Explanation:
Assume shaded region is X
Then :
X + Area of circle = area of square
X = area of square - area of circle
Find area of square:
Side length = 18mm
Area = 18 x 18 = 324
Find area of circle:
Side length of a square = the diameter of the circle = 18mm
And r(radius) = d/2 = 18/2 = 9
Area = pi x 9^2 = 254.34
Now find X
X = 324 - 254.34 = 69.66
