Answer 1

Answer 2

i ill fan and medal

Answer 3

im not really sure but my guess is 10 green marbles. not 20 b/c the amount of marbles picked is less and not 4 b/c thats how many were picked out of 50 so either 8 or 10 and 10 seems reasonable b/c its out of 50.

Answer 4

is the answer 10

Answer 5

Yes.

Answer 6

as the number of trials increase, the proportion comes closer to probability.
so setup a proportion :

\(\large \frac{4}{20} = \frac{x}{50}\)

Answer 7

solve \(x\)

Answer 8

10 is \(\large \color{red}{\checkmark}\)

Answer 9

yup. i like that

Answer 10

P(green)= 4/20 = 1/5
total no. of green marbles= (1/5) x 50
= 10
