Course: Statistics
The following table establishes the discrete probability distribution of a person working a certain number of days per month for a special program, according to the table determine which of the following statements are true

Days	20	21	22	23	24	25	26
Probability	0.01	a	0.1	0.15	b	0.23	0.26

I. If "a" is 0.06, then the value of "b" must be 0.21.
II. If "a" is 0.09, then the expectation is E(X) = 24.09.
III. If "b" is 0.19 then the expectation is E(X) = 23.81.

Select one:
a. Only I
b. Only II
c. Only III
d. I and II
e. I, II, III
