Question

If there are 1,000 raffle tickets sold for a fund raiser and you buy one ticket, what's the probability that you won't win?

Answer 1

The probability would be 999/1000 that you would not win 
 

Answer 2

Answer: $\frac{999}{1000}$

Step-by-step explanation:

Given: The total number of raffle tickets sold = 1,000

Number of tickets you bought = 1

Therefore, the probability that you will win is given by :-

$\text{P(win)}=\frac{\text{Number of tickets purchased by you}}{\text{Total tickets}}\\\\\Rightarrow\ \text{P(win)}=\frac{1}{1000}$

Now, the probability that you won't win is given by :-

$\text{P(Not win)}=1-\text{P(win)}\\\\\Rightarrow\text{P(Not win)}=1-\frac{1}{1000}\\\\\Rightarrow\text{P(Not win)}=\frac{999}{1000}$

Hence, the probability that you won't win=$\frac{999}{1000}$
