probability: 4/5
Explanation:
total marbles: 6 + 5 + 3 + 1 = 15 marbles
\\ not picking white marbles means, picking other marbles except white \\
solve:
[tex]\hookrightarrow \sf \dfrac{15-3}{15}[/tex]
[tex]\hookrightarrow \sf \dfrac{12}{15}[/tex]
[tex]\hookrightarrow \sf \dfrac{4}{5}[/tex]
Answer:
[tex]\frac{4}{5}[/tex]
Based on the given conditions, formulate:
[tex]1-\frac{3}{6+5+3+1}[/tex]
Calculate the sum or difference
[tex]1-\frac{3}{11+3+1}[/tex]
[tex]1-\frac{3}{14+1}[/tex]
[tex]1-\frac{3}{15}[/tex]
Cross out the common factor
[tex]1-\frac{1}{5}[/tex]
Find common denominator and write the numerators above common denominator
[tex]\frac{5}{5}-\frac{1}{5}[/tex]
Write the numerators over common denominator
[tex]\frac{5-1}{5}[/tex]
Calculate the sum or difference
[tex]\frac{4}{5}[/tex]
I hope this helps you
