Q1 . Determine the possible values of the given random variable and indicate as your answer whether the random variable is finite discrete, infinite discrete, or continuous.

A 6-sided die is tossed 300 times. Let the random variable X be the number of times that the 6-sided die shows 4 dots.

What are the possible values of X? ( options below )

• S = {X | X 0}
• S = {0, 1, 2, ... }
• none of these
• S = {0, 1, 2, ... 300}
• S = {X | 0 X 300}

Then it asked me to Classify X. ( options below )

• infinite discrete random variable
• continuous random variable
• finite discrete random variable

Q2. Determine the possible values of the given random variable and indicate as your answer whether the random variable is finite discrete, infinite discrete, or continuous.

A jelly bean is drawn at random and then replaced from a bowl of 6 pink and 7 blue jelly beans. Let the random variable X be the number of draws until a pink jellybean is picked.

What are the possible values of X?

• none of these
• S = {X | 1 X 13}
• S = {1, 2, 3, ... 13}
• S = {X | X 1 }
• S = {1, 2, 3, ... }

Classify X.

• continuous random variable in
• infinite discrete random variable
• finite discrete random variable
