Which set has the greatest range?
{10, 14, 8, 19, 22, 13, 44}
{119, 16, 50, 18, 29, 23, 37}
{11, 9, 31, 29, 15, 17, 20, 24}
{112, 6, 24, 20, 44, 15, 29}

D) {112, 6, 24, 20, 44, 15, 29}

Step-by-step explanation:

Range is the largest number minus the smallest number in the set.

Below I have found the range of each of the following answers. Once you figure out the ranges, the largest one is your answer.

A) 44 - 8 = 34

B) 119 - 16 = 103

C) 31 - 9 = 22

D) 112 - 6 = 106

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.

yes
