Questions & Step-by-Step Solutions
If a bag contains 4 green and 6 yellow marbles, what is the probability of picking a green marble?
Step 1: Count the number of green marbles in the bag. There are 4 green marbles.
Step 2: Count the number of yellow marbles in the bag. There are 6 yellow marbles.
Step 3: Add the number of green marbles and yellow marbles together to find the total number of marbles. 4 green + 6 yellow = 10 total marbles.
Step 4: To find the probability of picking a green marble, divide the number of green marbles by the total number of marbles. This is 4 (green marbles) divided by 10 (total marbles).
Step 5: Simplify the fraction 4/10. Both 4 and 10 can be divided by 2, which gives us 2/5.
