Question
A bag contains 7 red, 3, blue and 6 green balls.A ball is drawn randomly from the bag. What is the probability of drawing a green ball?
Solution
To calculate the probability of drawing a green ball, we need to know the total number of balls and the number of green balls.
Step 1: Calculate the total number of balls. The total number of balls is the sum of red, blue, and green balls. So, 7 (red) + 3 (blue) + 6 (green) = 16 balls.
Step 2: Identify the number of favorable outcomes. The question asks for the probability of drawing a green ball. The number of green balls is 6. So, the number of favorable outcomes is 6.
Step 3: Calculate the probability. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes. So, the probability of drawing a green ball is 6 (favorable outcomes) divided by 16 (total outcomes) = 0.375.
So, the probability of drawing a green ball is 0.375.
