What is 9 1/10 - 4 3/4

9 1/10 - 4 3/4 = 4.35 = 217.5/50 = 435/100

Step-by-step explanation:

9+(1/10) = 9.1

4+(3/4) = 4.75

9.10

-4.75

8.10+1

-4.75

=4.35

=217.5/50

=435/100

4.35

answer: a

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.
