Whole numbers are written on cards and then placed in a bag. tyra selects a single card, writes down the number. and then placed it back in the bag. she repeats this 62 times.
tyra calculates the relative frequency of each number card
which statement about tyra's experiment is true?
a. the out comes do not appear to be equally likely, so a uniform
probability model is a good
to represent the probabilities in tyra's experiment.
b. the outcomes do not appear to be equally likely, so a uniform propabililty model is not good model to represent the probabilities in tyra's experiment
c. the outcomes do not appear to be equally likely, so a uniform probability model is not good modelto repersent the probabilities in tyra's experiment.
c. the outcomes appear to be equally likely, so a uniform probability model is a good model to repersent the probabilities in tyra's experiment.
d. the outcomes appear to be equally likely, so a uniform probability model is not good model to represent the propabililtes in tyra's experiment.
