imagine you & your friend entered a raffle. you bought 10 tickets and your friend bought 20 tickets. there were a total of 300 tickets sold for the raffle what is the probability of you or your friend winning?
30/300 = 1/10
To determine the probability of either you or your friend winning the raffle, we need to calculate the ratio of the total number of tickets you both bought to the total number of tickets sold.
In this case, you bought 10 tickets and your friend bought 20 tickets, making a total of 10 + 20 = 30 tickets purchased. Since there were a total of 300 tickets sold, the probability of you or your friend winning is equal to the number of tickets you both bought (30) divided by the total number of tickets sold (300).
Therefore, the probability is 30/300, which simplifies to 1/10 or 0.10, meaning there is a 10% chance that either you or your friend will win the raffle.
