Answer:
P(X > 5) = 0.1164 to 4 d.p.
The parameters are defined in the explanation.
Step-by-step explanation:
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of potential hires = 10
x = Number of successes required = number of potential hires that have prior call centre experience = more than half; that is, x > 5
p = probability of success = probability that any potential hire will have experience = (11/30) = 0.367
q = probability of failure = probability that any potential hire will NOT have experience = 1 - p = 1 - 0.367 = 0.633
P(X > 5) = P(X=6) + P(X=7) + P(X=8) + P(X=9) + P(X=10)
Inserting the parameters and computing the probabilities for each of those values of X,
P(X > 5) = 0.11641775484 = 0.1164 to 4 d.p.
Hope this Helps!!!
Imagine a big solid and you cut out that one piece
the big solid is 9 by 12 by 3+4 (LWH)
so the volume is 9*12*7=756 cubic cm
the small slolid is 6 by 4 by 12 or 288 cubic cm
big-small=756-288=468 cubic cm
the volume is 468 cubic cm
2/3 = 0.66 repeating
3/4 = 0.75
3/4 is greater than 2/3
3/4 > 2/3
We need the system of equations and a picture of the graphs
