- d. Is this random variable discrete or continuous?

**a.**

To determine

List the outcomes of tossing a coin twice.

A coin is tossed two times.

The two possible outcomes of tossing a coin are, Head (*H*) and Tail (*T*). Thus, the outcomes of tossing a coin twice are,

To determine

Find a random variable that represents the number of heads occurring on the two tosses.

**c.**

To determine

Find the values that the random variable can take.

**d.**

To determine

Check whether the random variable is discrete or continuous.
