Abox contains 6 red and 5 blue marbles. another box contains 5 red and 8 blue marbles. one box is selected at random and from that bag, one marble is drawn. what is the probability that the marble drawn is blue?

The probability is 0.535

Step-by-step explanation:

Given that a box contains 6 red and 5 blue marbles. another box contains 5 red and 8 blue marbles. one box is selected at random and from that bag, one marble is drawn.

we have to find the probability that the marble drawn is blue.

The probability can be find by formula

=P(first box)P(blue marble drawn from box 1)+P(second box)P(blue marble drawn from box 2)

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
