The rental rates of a hotel room are $65 per day during the weekends and $85 per day during the weekends. A man rented a room in the hotel from Monday so Sunday. How much did he pay altogether?

so if you meant to sunday it would be

$555

but if you meant monday and sunday it would be

$150

Step-by-step explanation:

1-

a-$65x2=$130

b-$85x5=$425

c-$130+$425=555$

2-

a-$65+$85=$150

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.
