Alocal bakary has determined a probability distribution for the number of cheesecakes that they sell in a given day:

x= #sold 0 5 10 15 20
probability 0.25 0.47 0.12 ? 0.15

a. what is the probability of selling 15 cheesecakes in a given day?
b. what is the probability of selling at least 10 cheesecakes?
c. what is the probability of selling 5 or 15 chassescakes?
d. what is the peobaility of selling 25 cheesecakes?
e. give the expected number of cheesecakes sold in a day using the discrete probability distribution?
f. what is the probability of selling at most 10 cheesecakes?

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

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
