Answer:

[tex]\frac{1}{20}[/tex]


Step-by-step explanation:


Probability of BOTH BLUE is multiplication of the individual probabilities

  • P(Blue) in first jar is [tex]\frac{4}{16+4}=\frac{4}{20}=\frac{1}{5}[/tex]
  • P(Blue) in the second jar is [tex]\frac{25}{75+25}=\frac{25}{100}=\frac{1}{4}[/tex]

So, probability that a blue marble will be drawn from BOTH jars is [tex]\frac{1}{5}*\frac{1}{4}=\frac{1}{20}[/tex]

1/20 id the correct answer!
