A jar contains 10 red marbles and 20 blue marbles. If you take a random sample with replacement of two marbles from the jar and the first marble is blue, then the probability that the second marble is blue is p=19/29.

True or False

it could be true

Step-by-step explanation:

if there is 2 times as much blue marbles then red marbles it gives you a higher chance to get another blue marble

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
