Answer:

1/5 = 0.2 = 20%

Step-by-step explanation:

Given:

  • Yellow marbles = 2
  • Blue marbles = 4
  • Red marbles = 4
  • Total marbles = 10

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

[tex]\implies \sf P(yellow) = \dfrac{2}{10}=\dfrac15[/tex]

This can also be written as 0.2 or 20%

Answer:

[tex]Probability=0.2[/tex]

Step-by-step explanation:

Step 1:  List the given information

[tex]Total\ Marbles = 10[/tex]

[tex]Yellow\ Marbles = 2[/tex]

[tex]Blue\ Marbles = 4[/tex]

[tex]Red\ Marbles = 4[/tex]

Step 2:  Determine the probability of choosing yellow

[tex]Probability=\frac{Yellow\ Marbles}{Total\ Marbles}[/tex]

[tex]Probability=\frac{2}{10}[/tex]

[tex]Probability=\frac{1}{5}[/tex]

[tex]Probability=0.2[/tex]

Answer:  [tex]Probability=0.2[/tex]
