A bag of marbles contains only yellow, blue and green marbles. There are 4 yellow marbles and 2 blue marbles, and 1/3 of the marbles are green. If a marble is picked out at random, what is the probability it will be blue? Please give an answer ASAP!

2/9

Step-by-step explanation:

There are 4 yellow marbles and 2 blue marbles = 6 marbles

This is 2/3 of the marbles since 1/3 are green

2/3 of the total marbles are 6 marbles

2/3 * m = 6

m = 6 * 3/2 = 9

1/3 m = green marbles = 1/3 *9 = 3

4 yellow marbles and 2 blue marbles 3 green marbles = 9 marbles

P ( blue) = blue/total = 2/9

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
