Consider the following cumulative probability distribution.

x	0	1	2	3	4	5
P(Xx)	0.17	0.34	0.50	0.66	0.89	1

a.	CalculateP(X 4).(Round your answer to 2 decimal places.)

P(X 4)

b.	CalculateP(X= 4).(Round your answer to 2 decimal places.)

P(X= 4)

c.	CalculateP(2 X 4).(Round your answer to 2 decimal places.)

P(2 X 4)
