What's the score? Jermaine has entered a bowling tournament. To prepare, he bowls five games each day and writes down the score of each game,
along with the mean of five scores. He is looking at the scores from one day last week and finds that one of the numbers has accidentally been
erased.
The four remaining scores are 249, 254, 278, and 265. The mean score of the five games is 262. What is the missing score?

Step-by-step explanation:

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.

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m
