Consider the following cumulative probability distribution x
Consider the following cumulative probability distribution.
x. 0,1,2,3,4,5
P(X x). 0.09,0.31, 0.45,0.74,0.90,1
| a. | Calculate P(X 4). (Round your answer to 2 decimal places.) |
Solution
a)
As given,
P(x<=4) = 0.90 [ANSWER]
***************
b)
P(x = 2) = P(x<=2) - P(x<=1)
= 0.45 - 0.31 = 0.14 [ANSWER]
******************
c)
P(2<=x<=4) = P(x<=4) - P(x<=1)
= 0.90 - 0.31
= 0.59 [ANSWER]
