A beverage company puts one of the letters in the word MATH under each bottle cap. A prize is given to each person who collects all the letters. Which of the following could be used as a simulation for how many bottles it would take to collect all four letters?

A.
generating random integers from 1 to 100

B.
4 number cubes

C.
tossing a coin 4 times

D.
a spinner with 4 equal sections

D.  a spinner with 4 equal sections

Step-by-step explanation:

There are 4 letters in the word MATH, so each letter has an equal probability of 1/4.  Therefore, a spinner with 4 equal sections could be used to simulate the probability of selecting a letter.

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.
