Unit 4: Expected Value, Binomial Distribution, Continuous X

What is the area of this probability distribution?

Find the mean (expected value) of the probability distribution.

Is this binomial experiment? Shuffle a deck of 52 cards. Turn over the top card. Do not replace the card. Repeat the process 5 times. Let X = the card you observe.

Suppose you pay $1.00 to roll a fair die with the understanding you will get $3.00 back rolling a 4 or a 2, and nothing otherwise. What is the expected amount you win?

Identify whether the experiment involves a discrete or a continuous random variable.
