Questions & Step-by-Step Solutions
A jar contains 3 white, 2 black, and 5 blue balls. What is the probability of picking a blue ball?
Step 1: Count the number of white balls in the jar. There are 3 white balls.
Step 2: Count the number of black balls in the jar. There are 2 black balls.
Step 3: Count the number of blue balls in the jar. There are 5 blue balls.
Step 4: Add the total number of balls together: 3 (white) + 2 (black) + 5 (blue) = 10 total balls.
Step 5: Identify how many of those balls are blue. There are 5 blue balls.
Step 6: Calculate the probability of picking a blue ball by dividing the number of blue balls by the total number of balls: 5 (blue) / 10 (total) = 1/2.
