Two balls are selected from two black and two red balls. The probability that the two balls will have no black ball is:
Two balls are selected from two black and two red balls. The probability that the two balls will have no black ball is:
Show Hint
For sequential selection: \( \frac{2}{4} \times \frac{1}{3} = \frac{1}{6} \). Both methods give the same result.
