What does it mean to add? Give an example. What does it mean to subtract? Give an example. Draw a number bond. Label the parts of the number bond.

To add is to join (something) to something else so as to increase the size, number, or amount. i.e 5 + 3 = 8

To subtract is to take away (a number or amount) from another to calculate the difference. i.e 8 - 3 = 5

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.
