Ingrid and Thomas both enter a raffle where they get a chance to pull one winning ticket from a box. If there are 25 tickets in the box and tickets are not replaced, what is the probability that will pull a losing a ticket from the box? Write your answer as a simplified fraction.
There are 25 tickets in the box, and they will not be replaced. Therefore, after Ingrid or Thomas pulls a ticket, there will be 24 tickets left in the box. Since there is only one winning ticket, there are 24 losing tickets.
The probability of pulling a losing ticket is 24/25, which is already a simplified fraction.
So, the probability of pulling a losing ticket is 24/25.
