If a bag contains 4 green and 6 yellow marbles, what is the probability of picking a yellow 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 and yellow marbles together to find the total number of marbles. 4 green + 6 yellow = 10 total marbles.
Step 4: Identify how many of the total marbles are yellow. There are 6 yellow marbles.
Step 5: Calculate the probability of picking a yellow marble by dividing the number of yellow marbles by the total number of marbles. Probability = 6 yellow / 10 total = 6/10.
Step 6: Simplify the fraction 6/10 to its simplest form. 6/10 = 3/5.
