there are 8 red, 6 green, 10 blue marbles in a bag. A child keeps picking a ball at random and all marbles are equally likely to be picked. calculate the probability of picking a red marble
Pr(red)=reds/total=8/24=1/3
To calculate the probability of picking a red marble, we first need to determine the total number of marbles in the bag.
Given the information provided, there are 8 red marbles, 6 green marbles, and 10 blue marbles. Therefore, the total number of marbles in the bag is:
8 + 6 + 10 = 24
Next, we can determine the probability of picking a red marble. Since all marbles are equally likely to be picked, the probability of picking a red marble is the number of red marbles divided by the total number of marbles:
8 / 24 = 1/3
So, the probability of picking a red marble is 1/3, or approximately 0.333.
