Question 1056069
A continuous random variable X has the following probability density function:
f(x) = 1/4, 0 ≤ x ≤ 4'	
Find the following probabilities:
Sketch the density function as a rectangle with base = 4 and height = (1/4)	

a.	P(X ≤ 1) = 1*(1/4) = 1/4
-------------------------------------------
b.	P(X ≤ 2) = 2*(1/4) = 1/2
-------------------------------------------
c.	P(1 ≤X ≤ 2) = (2-1)*(1/4) = 1*(1/4) = 1/4
-------------------------------------------
d.	P(X = 3) = 3(1/4) = 3/4
