Step-by-step explanation:

The total amount of money is $63.90. Also, there are 3 friends.

In order to pay equally, divide $63.90 and 3 friends, so the answer would be dollars per friend

$63.90/3 friends = $21.3/friend

So the items you would drag would be:

2 $10 bills

1 $1 bill

3 $0.10 dimes

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.
