Urn contains 10 red balls and 5 green balls. A ball is drawn from the urnat random with replacement. If the ball is red, another red ball is added to theurn; if it is green, two more green balls are added to the urn. Then again a ballis drawn at random. Given that a red ball has been picked up in the seconddraw, what is the probability that a green ball was picked in the first draw

step-by-step explanation:

1. practice, practice & more practice

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
