[1] Probability space

You are given two six-sided dice to roll. For a given roll, what is the probability that the dice add to 3 or less?

If it helps, you may select the matching outcomes below.

[2] Adding probabilities

Manuel rolls a fair pair of six-sided dice. The sample space of all possible outcomes is shown above. Let A be the event that the first die is six and B be the event that the second die is four. What is P(A or B), the probability that the first die is six or the second die is four? 

[3] Independent probability

If you flip a coin and roll a 6-sided die, what is the probability that you will flip a heads and roll an even number?

[4] Dependent probability

A box contains 5 red jelly beans, 2 green jelly beans, and 6 blue jelly beans. If we choose a jelly bean, then another jelly bean without putting the first one back in the box, what is the probability that the first jelly bean will be green and the second will be red?
