Decide whether the random variable x is discrete or continuous: X represents the volume of water in a 20-ounce bottle.                

True or False. If the distribution is a probability distribution, then each probability is between 0 and 1?                  

4) Determine whether the distribution is a probability distribution: (in table form) x:  1  2  3  4  P(x): 0.25 0.48 0.23 0.11  

Construct population parameters of a Binomial Distribution given n= 5 and p = 0.6. Determine q, mean (μ), variance(σ^2), and standard deviation (σ).

A fair coin is flipped three times. Consider the following sequence of dependent trials: (use a tree diagram) Trial 1: Count the number of tails on the first flip.    Trial 2: Count the number of tails on the first 2 flips.  Trial 3: Count the number of tails on the first 3 flips.
