Trapezoid STUV with vertices S(-3,6), T(0,7), U(1,4), and V(-5,2): Right 7, Down 9

answer: slight chance that it will happen

step-by-step explanation:

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.

answer is  

minor arc – sw

major arc – stu

semicircle – wst

i got it down chief.

26 + 8 = 2*13 + 2*4 = 2*(13+4) = 2*(17)
