Question

in a lottery there are 5 prized tickets and 995 blank tickets.A person buys a lottery ticket. Find the probability of his winning a prize.

Answer 1

-Total prize tickets= 5
-Total blank tickets=995
-Hence,Total tickets=995+5=1000
Probability of winning a Prize= 5\1000

Answer 2

Given:

Number of prized tickets = 5

Number of blank tickets = 995

To find:

The probability of winning a prize

Solution:

To calculate the probability of winning a prize, we use the equation:

$\text{Probability}=\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Total number of outcomes = [5 + 995] = 1000

Putting values in the above equation, we get:

$\text{Probability of winning a prize}=\frac{5}{1000}\\\\\text{Probability of winning a prize}=0.005$

Hence, the probability of winning a prize in a lottery is 0.005
