Q
Q: In a lottery, there are 10 tickets, and 3 of them are winning tickets. If one ticket is drawn at random, what is the probability that it is a winning ticket?
Solution: The probability of drawing a winning ticket is 3/10.
Steps: 6
Step 1: Identify the total number of tickets. In this case, there are 10 tickets.
Step 2: Identify the number of winning tickets. Here, there are 3 winning tickets.
Step 3: To find the probability of drawing a winning ticket, use the formula: Probability = (Number of Winning Tickets) / (Total Number of Tickets).
Step 4: Plug in the numbers: Probability = 3 (winning tickets) / 10 (total tickets).
Step 5: Simplify the fraction if needed. In this case, 3/10 is already in its simplest form.
Step 6: Conclude that the probability of drawing a winning ticket is 3/10.
