Question

A bag contains 30 blue beads, 10 red beads, and 35 yellow beads. Julia pulls a bead out of the bag at random, puts it aside, and then pulls another bead out of the bag at random. What is the probability that Julia will pull two red beads out of the bag?

Answer 1

Answer:

So the probability of drawing a yellow bead is 3 (the number of cases that satisfy the requirement) divided by 8 (the total number of cases). Your answer is 3/8 (or .375 if you prefer).

Step-by-step explanation:

The probability of any event is the number of ways that event can happen divided by the total number of possible outcomes.

In this case, there are 8 beads in the bag and you are just removing one bead so there’s 8 different possible outcomes - one for each bead.

In 3 of the cases. the bead will be yellow. (In the other 5 cases it will be blue but we don’t care about that.)
