Question

A glass jar contains 1 red, 3 green, 2 blue and 4 yellow marbles.

cdquestions Admin · Accepted Answer

The total number of marbles is $ 1 + 3 + 2 + 4 = 10 $. A) Probability of getting a yellow marble is $ \frac{4}{10} = \frac{2}{5} $, not $ \frac{1}{5} $. B) Probability of getting a green marble is $ \frac{3}{10} $, which is correct. C) Probability of getting either a yellow or a green marble is $ \frac{4+3}{10} = \frac{7}{10} $, but this does not match the correct answer. D) Probability of getting a red or yellow marble is $ \frac{1+4}{10} = \frac{5}{10} $, which is $ \frac{3}{10} $ as given.
