For the following probability distribution, find X is at most 2... X 0 1 2 3 P(x) .2 .1 .3 .4 I am totally unsure how to get the answer which = .6

OpenStudy (zarkon):

you mean find the probability X is at most 2?

OpenStudy (anonymous):

yes

OpenStudy (zarkon):

.2+.1+.3

OpenStudy (anonymous):

Why? Because you are adding everything before the 2?

OpenStudy (zarkon):
