Introduction to probability

What is probability?

The likelihood of an event Occurring


Introduction to probability

Suppose you have 4 nickels, 2 dimes, and 6 quarters in your pocket. If you draw a coin randomly from your pocket, what is the probability that: a. You will draw a nickel? b. You will draw a half-dollar? c. You will draw a quarter?

d. You will draw a silver coin?


Introduction to probability

  • Event pocket. If you draw a coin randomly from your pocket, what is the probability that: – “drawing a specific coin”

    • Sample space – All possible out comes

    • P(E) = Number of favorable outcomes

      Total Number of Outcomes

      Ways to express probability

      • Fraction

      • Decimal

      • Percent

      • Odds

  • Theoretical Probability


  • Introduction to probability

    • You will draw a nickel? pocket. If you draw a coin randomly from your pocket, what is the probability that:

    • P(nickel) =

    • b. You will draw a half-dollar?

    • P(half-dollar) =

    • c. You will draw a quarter?

    • P(quarter) =

    • You will draw a silver coin?

    • P(silver coin) =


    Introduction to probability

    • Your pocket. If you draw a coin randomly from your pocket, what is the probability that:group’s job is to conduct an experiment to determine the following:

    • What is the probability of drawing each

    • “different” item in the bag?

    • Rules:

    • NO ONE LOOKS INSIDE!!!

    • ONLY 1 item can be drawn out at a time.

    • The Item MUST be put back in the bag before another Item is drawn.

    • Create a system for recording your results.


    Introduction to probability

    • NOW…… pocket. If you draw a coin randomly from your pocket, what is the probability that:

    • If I told you there are 40 chips in your bag….

    • Predict how many of each are in your bag

      • Red Chips

      • Blue Chips

      • Green chips

      • Purple chips

      • NOW COUNT!!!



    Introduction to probability

    Let the Good Times Roll!! Experimental Probability?

    Pick a Partner.

    Select which player will be ODD and which will be EVEN.

    Each turn consists of rolling 2 dice.

    One player rolls to find the product of the two dice.

    If the product is the even, then the player who predicted even gets a point. If the product is the odd, then the player who predicted odd gets a point.

    First player to 10 points WINS!!
