A bag of marbles contains 3 green marbles, 7 red marbles, 2 white marbles, and 10 black marbles. If a marble is randomly chosen, what is
the probability that the marble will NOT be green or white? Express the
probability as a fraction.

total 22 marbles, green and white ones are 5 so 22-5=17 so 17/22 or 17 out of 22

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
