  • 1

    When carrying out a number of trials in an experiment, what does the random variable X represent

    The number of successful trials

  • 2

    How is the random variable X modelled with a binomial distribution

    X ~ B(n, p), where n is the number of trials and p is the probability of success

  • 3

    What are the Conditions for using the binomial distribution

    Fixed number of trials (n), Exactly two possible outcomes, success and failure , Fixed probability of success (p), Trials are independent of each other

  • 4

    How else are n and p referred to as

    n can be called the index

  • 5

    What is the Probability Mass Function for a binomial distribution

    P(X = r) = (n/r)p^r(1 - p)^n- r

  • 6

    What is the symbol !

    Factorial - The product of a number and all of the positive integers smaller than it

  • 7

    What is an alternative Notation for (n/r)

    nCr

  • 8

    How can (n/r) be calculated

    n! / r!(n - r)!

  • 9

    How is the probability calculated from a binomial model using a calculator, when X is a specific value

    Enter "Menu", "7", "4", and "2" into the calculator, Enter the x value (e.g. 2), Enter the N value (e.g. 12), Enter the p value (e.g. ⅙), Solve to find the answer
