![\dfrac{l-k}{l}](https://tex.z-dn.net/?f=%5Cdfrac%7Bl-k%7D%7Bl%7D)
Step-by-step explanation:
The probability that Stephen wins a raffle is given by the expression: ![\dfrac{k}{l}](https://tex.z-dn.net/?f=%5Cdfrac%7Bk%7D%7Bl%7D)
Given an event A
P(A occurring)+P(A not occurring)=1
Therefore:
P(Stephen wins the raffle)+P(Stephen does not win the raffle)=1
Substituting our given probability, we obtain:
![\dfrac{k}{l}$ + P(Stephen does not win the raffle)=1\\P(Stephen does not win the raffle)$=1-\dfrac{k}{l}\\$Taking the Lowest common multiple of the right-hand side, we have:\\\\P(Stephen does not win the raffle)$=\dfrac{l-k}{l}](https://tex.z-dn.net/?f=%5Cdfrac%7Bk%7D%7Bl%7D%24%20%2B%20P%28Stephen%20does%20not%20win%20the%20raffle%29%3D1%5C%5CP%28Stephen%20does%20not%20win%20the%20raffle%29%24%3D1-%5Cdfrac%7Bk%7D%7Bl%7D%5C%5C%24Taking%20the%20Lowest%20common%20multiple%20of%20the%20right-hand%20side%2C%20we%20have%3A%5C%5C%5C%5CP%28Stephen%20does%20not%20win%20the%20raffle%29%24%3D%5Cdfrac%7Bl-k%7D%7Bl%7D)
