Ok for the first one, it is asking the probability of x being greater than 1 and less than 5.
In other words, what is the probability of x being either 2, 3, or 4?

benji · Answer

If you look at the graph and add the probabilities for 2, 3 , and 4, you should get the answer you are looking for.

goldandpinkiscool · Answer

Well, I know 2 is 0.4 but the other ones..I am not quite sure..I cannot really make it out...

benji · Answer

Well the lines seem to increase in increments of 0.02 if that helps.
