Questions & Step-by-Step Solutions

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?
  • 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.
  • Probability – The likelihood of an event occurring, calculated as the number of favorable outcomes divided by the total number of possible outcomes.
