add all the #’s together to get 13 and divide by the # of blue marbles(7)

Answer:

[tex] \huge \blue5 \blue3 \blue. \blue8 \blue\%[/tex]

Step-by-step explanation:

to understand this

you need to know about:

  • simple probability
  • percent
  • PEMDAS

tips and formulas:

  • [tex]probability = \frac{Number \: of \: ways \: it \: can \: happen}{Total \: number \: of \: outcomes} [/tex]
  • [tex]\% = \frac{1}{100} [/tex]

let's solve:

total marbles=7+2+4=13

blue marbles=7

therefore the probability is

[tex] \frac{7}{13} [/tex]

let's convet it in percentage

[tex] \frac{7}{13} \times 100 \: \: \%[/tex]

[tex]53.8\%[/tex]
