    PROBABILITY Distributions

    This is from a grade 12 Data Management class. Easy explanations would be helpful. Thanks to anyone and everyone.

    1) Explain why recording the value rolled for each of 50 rolls of a 6-sided die is not a binomial experiment. Describe a binomial experiment that involves rolling a die 50 times.


    2) Describe two different simulations, using a non-technology method and a technology method that would model the binomial distribution for the number of donations obtained by a volunteer for a charity if the neighbourhood being canvassed has a long-term contribution rate of 30% and the volunteer visits 20 homes.


    3) A salesman has a 20% probability of making a sale to any customer who enters his department. On a typical day, he will meet 30 customers. What minimum number of sales will he have an 88% certainty of making for any given day?

    Because, in the binomial experiment we record how many out of how mant times a favorable event happens. Over here we simply throw it a single time.

    If you want to turn this into a binomial experiment you need for example 6 dice and throw them and record the number of one's that appear in fifty throws.
