If you have5 red marbles and 7blue marbles in a bag what is the probability of getting a red one
5 of 12 marbles are red
P(red) = 5/12
Sorry if you take one marble from a bag that had a total of 12. 5 red and 7 blue what is the probability as a fraction of getting 1 red?
To find the probability of getting a red marble, you first need to determine the total number of marbles in the bag. In this case, there are 5 red marbles and 7 blue marbles, so the total number of marbles is 5 + 7 = 12.
Now, you need to determine the number of favorable outcomes, which is the number of red marbles. In this case, there are 5 red marbles.
The probability of getting a red marble can be calculated by dividing the number of favorable outcomes (5) by the total number of outcomes (12):
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 5 / 12
Therefore, the probability of getting a red marble is 5/12.
