Questions & Step-by-Step Solutions

In a lottery, there are 10 tickets, of which 3 are winning tickets. What is the probability of selecting a winning ticket?
  • Step 1: Identify the total number of tickets in the lottery. 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 selecting 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 possible. In this case, 3/10 is already in its simplest form.
  • Step 6: Conclude that the probability of selecting a winning ticket is 3/10.
