Suppose that 1is a Bernoulli random variable representing a fair coin. 1takes the value 1 if the coin lands "heads" and the value 0 if the coin lands "tails".

Suppose 2is a Bernoulli random variable representing a different fair coin. 2takes the value 1 if the second coin land "heads" and the value 0 if the coin lands "tails".

Suppose that =1+2. That is, suppose that Y counts the total number of heads that are showing.

Then, match the following events with their probabilities.
