Justin has 23 one dollar bills. He wants to give each of his 3 children the same number of bills. How many bills can he give each child? How many bills will Justin have remaining?

If Justin give's each of his children 7 one dollar bills, He will have 2 one dollar bill remaining

Step-by-step explanation:

since he has 3 children he have to divide 23 by 3 so we count until we get a number close to 23 but not greater because we have to subtract that number from 23

3.6.9.12.15.18.21.24.27.30.

Now that we found our number closest to 23 without going greater than 23 we subtract it from 23

     23

  -  21

       2

so that's how we got the remaining amount of money but we count how many time's we multiplied to get 21, that's 7 which is the amount each children gets.

I hope this helps :)

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.
