Question
A bag contains 45 counters, of which 3 are yellow.
Find the probability to pick a counter from the bag which is not yellow.
Solution
Step 1: Identify the total number of outcomes. In this case, there are 45 counters in the bag.
Step 2: Identify the number of favorable outcomes. Here, we are looking for the probability of picking a counter that is not yellow. Since there are 3 yellow counters, there are 45 - 3 = 42 counters that are not yellow.
Step 3: The probability of an event is given by the ratio of the number of favorable outcomes to the total number of outcomes. So, the probability of picking a counter that is not yellow is 42/45 = 0.9333.
So, the probability to pick a counter from the bag which is not yellow is approximately 0.9333 or 93.33%.
