### How to Calculate the Probability of Winning the Lottery ?

Have a look at the detailed explanation to calculate the lottery probability for any given number.

• Apply, the lottery formula.
• Substitute the values in the formula and perform math operations.
• Finally, you will get the answer.

### Lottery Formula

Here we are giving the lottery formula that helps to find the winning chances of the lottery.

Lottery = C(n,r) / [C(r,m) * C(n-r, r-m)]

Where,

m is the number of balls to be drawn

n is the number of matches

r is the number of balls in pool

Question:

If we have 28 balls in a pool and from that 20 balls are drawn from 15 matches. Find the chances of winning the lottery?

Solution:

Given that,

r = 28

n = 30

m = 20

Use the Lottery formula

Lottery = C(n,r) / [C(r,m) * C(n-r, r-m)]

Lottery = C(30,28) / [C(28,20) * C(30-28,28-20)]

Lottery = 3108105
