Urn 1 contains 5 red balls and 3 black balls. urn 2 contains 3 red balls and 1 black ball. urn 3 contains 4 red balls and 2 black balls. if an urn is selected at random and a ball is drawn, find the probability it will be red.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
