Detailed Solution

Given,
Probability of selecting a red marble=

\frac{2}{15}

Probability of selecting a blue marble =

\frac{4}{15}

Probability of selecting a white marble = Total probability - [Probability of selecting a red marble Probability of selecting a blue marble]

= 1 - [\frac{2}{15} + \frac{4}{15}]

= 1 - \frac{6}{15}

= \frac{9}{15}

= \frac{3}{5}

Hence, the probability of selecting a white marble

= \frac{3}{5}

Correct option is 3.
