An experiment involves picking a card from a selection of cards numbered 10, 20, and 30. In equation form, what is the probability model for this experiment? List the values of x in ascending order.

1 answer

Let X be the random variable representing the card picked, then the probability model is:

P(X=10) = 1/3
P(X=20) = 1/3
P(X=30) = 1/3

The values of x in ascending order are: 10, 20, 30.
