Answer: The chance of Mohan winning a prize is 0.25 or 25%.
Explanation:
To calculate the chance of winning a prize, we need to consider the total number of outcomes and the number of favorable outcomes.
In this case, Mohan has 3 tickets out of a total of 3 prizes and 9 blanks. To find the chance of winning a prize, we can calculate the probability using the following formula:
Probability = Number of favorable outcomes / Total number of outcomes
Number of favorable outcomes: Mohan has 3 tickets, and each ticket represents a favorable outcome (a prize).
Total number of outcomes: The total number of outcomes is the sum of the number of prizes and blanks, which is 3 prizes + 9 blanks = 12.
Plugging these values into the formula:
Probability = 3 / 12 = 1/4 = 0.25
Therefore, the chance of Mohan winning a prize is 0.25 or 25%.
I hope this helps :)
