Answer:
x=4C/πs^2
Step-by-step explanation:
C=1/4πs^2x
1) Divide both sides by π and s^2:
C/πs^2=1/4x
2) Multiply both sides by the reciprocal of 1/4: (4)
4C/πs^2=x
Answer:
a) P=0.3174
b) P=0.4232
c) P=0.2594
d) The shape of the hypergeometric, in this case, is like a binomial with mean np=1.
Step-by-step explanation:
The appropiate distribution to model this is the hypergeometric distribution:

a) What is the probability that none of the questions are essay?

b) What is the probability that at least one is essay?

c) What is the probability that two or more are essay?

Hope this helps with the answer to your question:)
