Learn with an example

You pick a card at random. Without putting the first card back, you pick a second card at random.

What is the probability of picking a 4 and then picking a 2?

Write your answer as a fraction or whole number.

The probability is the number of favorable outcomes out of the number of possible outcomes.

Find P(4). There are 3 cards, numbered 2, 3, and 4.

P(4)

Now find the probability of picking the 2 once you have already picked the 4.

After you have picked the 4, the following cards will remain:

There are 2 cards remaining. One of those cards is the 2.

Find the probability of picking a 4 and then picking a 2. Multiply P(4) by P(2).

P(4) x P(2)
