An experiment involves picking a card from the number cards 2, 4, 6, 10. In equation form.

What is the probability model for this experiment?
f(x) = □, where x = 2, 4, 6, 10

The probability model for this experiment is:

f(x) = 1/4, where x = 2, 4, 6, 10

This is because there is 1 card of each number in the set of 2, 4, 6, and 10, and there are a total of 4 cards. Therefore, the probability of picking any particular number card is 1/4.
