Three identical bags each contain two marbles. One bag has two white marbles, one has two black marbles, and one has one of each. You are given a bag at random and draw a white marble. What fraction of the time will the second marble you draw from that bag also be white?

bye

but there’s no any figure there!

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
