Q
Q: If a bag contains 2 white, 3 black, and 5 blue balls, what is the probability of drawing a blue ball?
Solution: The total number of balls is 2 + 3 + 5 = 10. The probability of drawing a blue ball is 5/10 = 1/2.
Steps: 6
Step 1: Count the number of white balls in the bag. There are 2 white balls.
Step 2: Count the number of black balls in the bag. There are 3 black balls.
Step 3: Count the number of blue balls in the bag. There are 5 blue balls.
Step 4: Add the number of all the balls together: 2 (white) + 3 (black) + 5 (blue) = 10 total balls.
Step 5: Identify how many of the total balls are blue. There are 5 blue balls.
Step 6: Calculate the probability of drawing a blue ball by dividing the number of blue balls by the total number of balls: 5 (blue) / 10 (total) = 1/2.
