1. A bowl contains both red and green marbles. How many green marbles are in the bowl?
1) If a marble is randomly selected from the bowl, the probability that a green marble will be selected is 1/3.
2) If one green marble is removed from the bowl and then a marble is selected at random from those remaining in the bowl, the probability that a green marble will be selected is 1/5.
----------------
2. There is a linear relationship between variable r and variable s. When r has a value of 6, s has a value of 30. When r has a value of 24, s has a value of 60. What is the value of r that corresponds to a value of s of 100?
----------------
3. If n is a positive integers, what is the largest value of n such that 2n is a factor of 20!?
I have solved the first one and got the answer Green balls = 2 and Red =4
Is their any rule to solve the second problem? How to build the equation for that?
provide your explanations too, thanks..
