Probability Level 2

In a lottery,a person chooses 5 different numbers at random from 1 to 15 and if these 5 numbers match with 5 numbers already fixed by the lottery committee,he wins the prize. Then the probability of winning the prize in the game is:

1 3003 \frac{1}{3003} 5 3001 \frac{5}{3001} 5 3003 \frac{5}{3003} 1 3001 \frac{1}{3001}

Number of favorable cases = 1

Number of possible case of selecting 5 numbers from 1 to 15 = 15C5 = 3003

P(winning the prize) = 1 3003 \frac { 1 }{ 3003 }
