A. 0.5m

B. 1.5m

C. 3m

D. 3.5m

Step-by-step explanation:

Given

Selling Price = 3 * Amount she paid

Required

Determine the selling price

If she gets a discount of 50%, then she pays 50% (i.e. 100 - 50%).

She sells at three times that amount.

So, the selling price is:

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.
