Answer:
The probability that the sixth customer buys sour milk is
.
Step-by-step explanation:
The grocery store has a total of 10 cartons of milk.
The number of cartons of milk that are sour is, 2.
- If none of the sour cartons of milk were bought by the first 5 buyers, then the probability of this event is:
P (Both the sour cartons are available to be sold to the sixth customer)
= 
- If only one sour carton of milk is sold to the first 5 buyers then the probability is:
P (Only one sour cartons is available to be sold to the sixth customer)
= 
- If both the sour carton of milk is sold to the first 5 buyers then the probability is:
P (None of the sour cartons is available to be sold to the sixth customer)
= 
Compute the probability that the sixth customer buys sour milk:
= P (Both sour milk is available for the 6th customer) +
P (Only one sour milk is available for the 6th customer) +
P (None of the sour milk is available for the 6th customer)

Thus, the probability that the sixth customer buys sour milk is
.
a) C(0.5) = 39, C(2) = 39, C(4) = 69
b) Answers in part (a) represents the values of C at x = x₀
c) C(x) is continuous at x = 2
C (x) = 39 for 0 ⩽ x ⩽ 2
Since x = 0.5 is in the range 0 ⩽ x ⩽ 2:
C(0.5) = 39
Since x = 2 is in the range 0 ⩽ x ⩽ 2
C(2) = 39
Since x = 4 is in the range x > 2
C(4) = 39 + 15(x - 2)
C(4) = 39 + 15 (4 - 2)
C(4) = 39 + 15(2)
C(4) = 39 + 30
C(4) = 69
b) The answers in part A represents C(x). That is, the values of C at x = x₀
c) Is C(x) continuous at x = 2
C(2) = 39

Since
, the function C(x) is continuous at x = 2
