Answer:

28/85

Step-by-step explanation:

First Urn

Total number of balls = 7+10 =17

Number of white balls =7

P(White) = 7/17

SecondUrn

Total number of balls = 8+2=10

Number of white balls =8

P(White) = 8/10

Therefore, if a ball is drawn at random from each urn, the probability that both balls are white will be:


\begin{gathered} =(7)/(17)*(8)/(10) \\ =(56)/(170) \\ =(28)/(85) \end{gathered}
