Question 1104041:
A random variable x has this probability distribution, x 0 1 2 3 4 5 P(x) a 0.25 0.28 0.15 0.05 0.01

A random variable x has this probability distribution,  

x	0	   1	   2	    3	    4	    5
P(x)	a	0.25	0.28	 0.15	 0.05    0.01

The sum of the P(x) values must total 1, so the equation is

a+0.25+0.28+0.15+0.05+0.01 = 1

Solve for a.
