There are 22C7 ways. (7^22)C= (20×19×18×17×16×15×14)/(1×2×3×4×5×6×7)= 77520 So, Probability of winning the lottery = 1 / 77520

Total number of choices = 22C7 = 170544. Out of this only 1 will match with the prefixed number. Hence the required probability is 1/170544.

There are total 22C7choices that she has to choose from out of which only one will win her the prize. So, the chance of winning a prize is 1/(22C7) = 1/170544
