Find the probability

key notes :

  • The probability is the number of favorable outcomes out of the number of possible outcomes.

Learn with an example

📚 If you flip a coin, what is the probability that it will land on tails?

📚 Write your answer as a fraction or a whole number. With fractions, use a forward slash ( / ) to separate the numerator and denominator._________

  • There are 2 possible outcomes: heads or tails.
  • There is 1 favorable outcome: tails.
  • The probability is 1 out of 2, or 1/2.

📚 If you roll a 6-sided die, what is the probability of rolling an even number?

📚 Write your answer as a fraction or a whole number. With fractions, use a forward slash ( / ) to separate the numerator and denominator._________

  • There are 6 possible outcomes: 1, 2, 3, 4, 5, 6.
  • There are 3 favorable outcomes: 2, 4, 6.
  • The probability is 3 out of 6, or 3/6.

📚 If you roll a 6-sided die, what is the probability of rolling a two?

📚 Write your answer as a fraction or a whole number. With fractions, use a forward slash ( / ) to separate the numerator and denominator.______

  • There are 6 possible outcomes: 1, 2, 3, 4, 5, 6.
  • There is 1 favorable outcome: 2.
  • The probability is 1 out of 6, or 1/6.
