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]
