Let r be the red marble, b the blue marble, g the green marble.
possible outcomes={r,r,b,b,b,b,b,b,b,g,g,g,g,g,g}

belka [17]

Answer:

0.195

Step-by-step explanation:

Given:

For ; sample size, n = 9 ;

Standard Error (S. E) = 0.39

S. E = σ / sqrt(n)

σ = standard deviation

0.39 = σ / sqrt(9)

σ = 0.39 * 3

σ = 1.17

Therefore, For n = 36

S. E = 1.17 / sqrt(36)

S.E = 1.17 / 6

S.E = 0.195

kodGreya [7K]
Here is the solution for the given problem above.
Given that in the whole pizza, 2/5 of it is pepperoni (which makes 3/5 of the pizza has different flavor). What we are going to find is how much of all the pizza ordered was eaten by the kids, since only 1/3 of the pepperoni pizza is eaten by them. So to solve this, we will multiply 1/3 by 2/5 and the answer would be 2/15. Therefore, the answer is 2/15 of the pizza was eaten by the kids.
