1150

Step-by-step explanation:

First how many subscribers does he have? 200+ (40-10=30)=230

230*5=1150

$1150

Step-by-step explanation:

To find the number of subscribers for this month, let’s take the number of subscribers from last month 200 , add the new subscribers 40 and subtract the people who cancelled 10

The number of subscribers this month is 200+40-10=230

Each subscriber pays $5 so the revenue for this month is 230 × $5=$1150

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.
