Probability distribution,

Question

x	P(x)
0	0.25
1	0.3
2	0.1
3	0.35

Find the expected value of this probability distribution. Round your answer to one decimal place.

I keep getting this answer wrong. Help

Answer 1

0(.25) + 1(.3) + 2(.2) + 3(.35)

= 0 + .3 + .2 + 1.05

= 1.55 = the weighted average = expected value

but rounded to one decimal place is 1.6

round up if half way or more between integers.
