The lcd for the fractions 1/3, 3/4, 5/32, and 8/9 is

we know that

The LCD is the LCM (least common multiple) of all the denominators.

we have

So

The LCM of is ,

which is the multiple of the highest power of prime factors from all of the given numbers

therefore

the answer is

2

step-by-step explanation:

1+1=2

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.
