  • Step 3: To find the probability of drawing a winning ticket, use the formula: Probability = Number of winning tickets / Total tickets.
  • Step 4: Substitute the numbers into the formula: Probability = 10 / 100.
  • Step 5: Simplify the fraction 10 / 100 to get 1 / 10.
  • Probability – The likelihood of an event occurring, calculated as the ratio of favorable outcomes to total possible outcomes.
  • Basic Arithmetic – The ability to perform simple calculations, such as division and simplification of fractions.
