The correct option is B.
W(x)=24x+8
Answer:
a) 120
b) 10
c) 1/12
Step-by-step explanation:
The number of ways that a sample of r can be selected from a population of n is:
nCr = n! / (r! (n−r)!)
a) 3 people selected from a group of 10
₁₀C₃ = 120
b) 3 women selected from a group of 5
₅C₃ = 10
c) Of the 120 committees that can be chose, 10 are all women. So the probability is 10/120 = 1/12.
4/8 = 20/L cross multiply 4L = (20)(8) 4L = 160 L = 160/4 L = 40 length is 40
Hope this helps!!
