if a bag contains 8 red marbles, 6 blue marbles and 9 green marbles, what is the probability of choosing a blue marble??
# of blue marbles/total number of marbles.
you mean 6/23?
To find the probability of choosing a blue marble, we need to know the total number of marbles in the bag, as well as the number of blue marbles in the bag.
In this case, we are given that the bag contains 8 red marbles, 6 blue marbles, and 9 green marbles. So the total number of marbles in the bag can be calculated by adding up the number of each color: 8 + 6 + 9 = 23 marbles.
The probability of choosing a blue marble can be calculated by dividing the number of blue marbles by the total number of marbles:
Probability of choosing a blue marble = Number of blue marbles / Total number of marbles = 6 / 23
Hence, the probability of choosing a blue marble from the bag is 6/23.
