Re: Elementry Probability

In each case you want to divide the number of favorable outcomes by the total number of outcomes.

When drawing a card, we know there are 52 possible outcomes. Can you state the number of favorable outcomes for each case?

For example, if we are asked for the probability that we will draw a black 9, we use the fact that there are 2 black 9's and we than state the probability as:

Can you now proceed?
