Question
A bag with 12 marbles has 5 red marbles, 3 blue marbles, and 4 yellow marbles. A marble is chosen from the bag at random. What is the probability that it is red?Write your answer as a fraction in simplest form.
Solution
The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes.
In this case, the favorable outcome is drawing a red marble, and there are 5 red marbles. The total number of outcomes is the total number of marbles, which is 12.
So, the probability (P) of drawing a red marble is calculated as follows:
P(Red) = Number of red marbles / Total number of marbles = 5 / 12
So, the probability of drawing a red marble is 5/12.
