Answer:
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.)
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).
