A bag of marbles contains 6 blue marbles, 2 yellow marbles, 4 red marbles, and 1 green marble. What is the probability of reaching into the bag and selecting a yellow marble?
P(yellow) = yellow/total = 2/(6+2+4+1) = 2/13
I have a bag of marbles with 4green,3red,2blue,and1 yellow
I have a bag of marbles with 4green,3red,2blue,and1 yellow find the p(red)
To calculate the probability of selecting a yellow marble from the bag, we need to divide the number of yellow marbles by the total number of marbles in the bag.
Step 1: Find the total number of marbles in the bag.
Add up the number of blue, yellow, red, and green marbles:
6 blue + 2 yellow + 4 red + 1 green = 13 marbles
Step 2: Find the number of yellow marbles.
The bag contains 2 yellow marbles.
Step 3: Calculate the probability.
Probability = Number of favorable outcomes / Total number of possible outcomes
In this case, the favorable outcome is selecting a yellow marble, and the possible outcomes are selecting any marble from the bag.
Probability = Number of yellow marbles / Total number of marbles
Probability = 2 / 13 ≈ 0.154
Therefore, the probability of reaching into the bag and selecting a yellow marble is approximately 0.154 or 15.4%.
