Draw a tree diagram for the problem listed above and you will be able to solve the problem fairly easily.
There are four coins in a jar: a penny, a nickel, a dime, and a quarter. One coin is removed at random. Without replacing the first coin, a second
coin is removed.
Find the probability that the total value of the two coins selected is
(1) 11 cents
(2) greater than 35 cents
(3) at most 30 cents
Yes. You solve the problem using conditional probability as the the experiment performed only involve 2 stages.

But i will strongly advice you to draw the tree diagram.
