Andrew has 37$ in his bank account and writes a check for 87$ . After the check has been cashed , what will the bank balance show?

-50

Explaination: when you write a check, you are withdrawing money.

This means that Andrew will have -50 in his bank balance.

You add the 37 dollars currently in his bank account, but you also add the -87, (in this case is negative since you are withdrawing), which makes your answer -50.

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.
