Ellen takes a multiple-choice quiz that has 5 questions, with 3 answer choices for each question. What is the probability that she will get exactly 2 answers correct by guessing? Probabilities should be entered as
fractions in simplest form, decimals rounded to the nearest thousandth, or percents rounded to the
nearest tenth.
The probability that Ellen will get any one answer correct is
So, the probability that Ellen will get exactly 2 answers correct by guessing is

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
