Question

Probability (up to one decimal place) of consecutively picking 3 red balls without replacement from a box containing 5 red balls and 1 white ball is ______

Answer 1

Probability of consecutively picking 3 red balls without replacement (P)

P \(= \frac{5}{6} \times \frac{4}{5} \times \frac{3}{4} = \frac{1}{2}\)

∴ Probability of consecutively picking 3 red balls without replacement (P) is 0.5 .
