Answer Verified Verified
Favourable outcomes by total outcomes is probability So the number of white balls by total number of balls gives you the probability of white balls.

“Complete step-by-step answer:”
Given that a bag contains 4 white and 2 black balls.
\[\therefore \]Number of white balls = 4
Number of black balls = 2
\[\therefore \]Total number of balls = 4 + 2 = 6.
We need to find the probability of picking up a white ball,
= Number of white balls/Total number of balls\[=\dfrac{4}{6}=\dfrac{2}{3}\]
\[\therefore \]The probability of picking up a white ball from a bag of 4 white balls and 2 black balls is \[\dfrac{2}{3}\].
Note: If the question was to find the probability of picking up a black ball
=Number of black balls/Total number of balls\[=\dfrac{2}{6}=\dfrac{1}{3}\]
