One of the tokens for a board game is a circle containing 5 congruent triangles, as modeled below. Which measurement is closest to the area in square centimeters of the token not covered by the triangles?
25.76 cm2
2.5 cim2
110.6 cm2
28.27 cm2

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.

the correct answers i think are b. and d.

give me brainliest if it is correct!
