Step-by-step explanation:
The pdf of the number of cheesecakes that they sell in a given day: by a bakery are as follows:
X 0 5 10 15 20
P 0.25 0.47 0.12 k 0.15
Use total prob =1, to find k .
k = 0.01
a) the probability of selling 15 cheesecakes in a given day = 0.01
b. What is the probability of selling at least 10 cheesecakes =P(X≥10)
= 0.28
c. the probability of selling 5 or 15 chassescakes P(5)++P(15)=0.48
d. the probaility of selling 25 cheesecakes = 0
e. Give the expected number of cheesecakes sold in a day using the discrete probability distribution?
=
f. the probability of selling at most 10 cheesecakes
=P(X≤10)
= 0.84
