Answer:

Given:

  • 9 red marbles
  • 8 blue marbles
  • 12 green marbles

⇒ total marbles = 9 + 8 + 12 = 29


\sf Probability\:of\:an\:event\:occurring = (Number\:of\:ways\:it\:can\:occur)/(Total\:number\:of\:possible\:outcomes)

Part (a)


\sf P(green)=(12)/(29)

Part (b)


\sf P(red)=(9)/(29)


\sf P(green)=(12)/(29)


\implies \sf P(red)\:or\:P(green)=(9)/(29)+(12)/(29)=(21)/(29)

Part (c)


\begin{aligned}\sf P(not\:red)&= \sf1-P(red)\\ & = \sf 1-(9)/(29)\\ & = \sf(20)/(29)\end{aligned}
