Answer:

\pink{Given:-}

________________________________

\green{Green\:Ball=2}

 \red{Red\:Ball=5}

{Black\:Ball=8}

_________________________

\blue{Total\:Balls=15}

  1. Probability Of Green Balls:-

Probability of any Event P(E) = n(E) / n(S). ...

P(E) = Probability of Event. n(E) = Total number of required outcomes. n(S) = Total number of Possible outcomes.

 P(E)=\frac{2}{15}

________________________________

2.Not A Red Ball:-

No. Of Red Ball-Total No.Of Balls

No. Of Red Ball-Total No.Of Balls5-15=10

Probability of any Event P(E) = n(E) / n(S). ...

Probability of any Event P(E) = n(E) / n(S). ... P(E) = Probability of Event. n(E) = Total number of required outcomes. n(S) = Total number of Possible outcomes.

P(E)= \frac{10}{15}  =  \frac{2}{3}
