Question
In a lottery there are 15 prizes and 30 blanks. A lottery is drawn at random. Then, the probability of a getting prize is_____.
Hint:
We have the find the probability of getting the prize if the lottery is picked randomly. Firstly we will find the total number of outcomes which is the sum of the prizes and blanks, then we will find the number of possible outcomes i.e. the number of prizes. Further we will find the probability by dividing number of possible outcomes by total number outcome.
The correct answer is:
total no. of outcome = 15 +30 = 45
no. of possible outcome(no. of prizes) = 15
Probability =
So, the probability of getting prize if the lottery is picked randomly is .
