A jar contains 8 red marbles numbered 1-8 and 6 blue marbles numbered 1-6. Marble drawn at random from the jar. Find the probability marble is odd numbered
There are a total of 14 marbles in the jar. Out of these, 4 are odd numbered red marbles (1, 3, 5, 7) and 3 are odd numbered blue marbles (1, 3, 5). Therefore, the probability of drawing an odd numbered marble is:
P(odd numbered) = (4 + 3) / 14
P(odd numbered) = 7/14
P(odd numbered) = 1/2
So the probability of drawing an odd numbered marble is 1/2 or 50%.
