In a lottery, a person chooses six different numbers at random from 1 to 20. If these six numbers match with the six numbers already fixed by the lottery committee he wins the prize. What is the probability of winning the prize in the game ?
Number of ways in which 6 numbers can be chosen from 20 = 20C6=38760
Out of which only 1 is correct.
Hence, p(E)=138760
