Q: In a lottery, there are 100 tickets, and 10 of them are winning tickets. What is the probability of selecting a winning ticket?
Solution: The probability of selecting a winning ticket is the number of winning tickets divided by the total number of tickets, which is 10/100 = 1/10.

Step 2: Identify the number of winning tickets. Here, there are 10 winning tickets.
Step 3: To find the probability of selecting a winning ticket, use the formula: Probability = (Number of Winning Tickets) / (Total Number of Tickets).
