Introduction to Probability Distributions - Random Variables

In your own words, describe what a random variable is:

Give an example of a random variable:

Which of the following variables are continuous random variables (select all that apply):

• Number of ice cream cones a customer orders
• Number of minutes each customer spends deciding which ice cream to buy
• Number of ringgit spent by each customer
• Number of scoops of ice cream each customer buys
• Number of kilometers each customer spent travelling to the ice cream shop

Describe (in words) what the mathematical notation " P(X > 2) " means:

Which of the following statements is false?

• A probability distribution shows the probability of each outcome in the experiment or sample space
• If the possible values of a random variable X are 0,1, 2, 3, 4 or 5, then P(X < 2) = P(X=0) + P(X=1)
• A random variable is one that is not measurable
