Kryger [21]

Answer:

The expression would give the probability that one marble is yellow and the other marble is red is,

P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)

Step-by-step explanation:

A bag contains eight yellow marbles, nine green marbles, three purple marbles, and five red marbles. So in total there are 25 marbles.

Hence,

Probability of getting yellow ball = P(Y)=\dfrac{8}{25}

Probability of getting red ball = P(R)=\dfrac{5}{25}

Probability that one marble is yellow and the other marble is red is,

P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)=\dfrac{8}{25}\cdot \dfrac{5}{25}+\dfrac{5}{25}\cdot \dfrac{8}{25}=0.128
