Ok: the question is basically asking what is the percentage of the black marbles he had pulled with replacements. You look at the graph and count how many black marbles he pulled,6, and then find the total of marbles he pulled after the experiment ,20. So, you take (6/20) which then gives you an answer of .3 which is a 30%.

Alexus [3.1K]

The answers to the questions on how she would use the colored chips are given here:

  • brochure 4 blue chips
  • writing a new article 6 yellow chips
  • designing a computer presentation 10 red chips

<h3>How to solve for the values</h3>

For the first percentage

20 / 100 = x/20

= 20 * 20 = 100x

400 = 100x

divide through by 100

x = 400/100

x = 4

For the second percentage

30/100 = x/20

600 = 100x

x = 600/100

x = 6

For the last

50/100 = x/20

1000 = 100x

x = 10

The proof is that 6 + 4 + 10 still gives us 20
