Astudent randomly draws a card from a standard deck and checks to see if it is his favorite suit. he then returns the card to the deck, shuffles, and repeats the experiment. he performs the experiments 30 times. can the probability of drawing his favorite suit be found by using the binomial probability formula? why or why not?
yes. the events are dependent; however, the 5% guideline can be applied to this situation.
no. the trials are fixed, but the probability of success changes for every trial.
no. the probability of success remains the same for every trial, but the trials are not fixed.
yes. the outcomes can be classified into two categories, the trials are fixed, and the events are independent.
are you sure this is middle schools math? ?
a. this is the arithmetic sequence, because
the first term of this sequence is and the difference is 0.3.
b. since this is not arithmetic sequence.
c. since this is not arithmetic sequence.
d. since this is not arithmetic sequence.
the correct answer is 1.68
simplify divide 37÷22
