Best answer
Correct Answer - Option 1 : 2/5

Concept:

If S is a sample space and E is a favourable event then the probability of E is given by:

\(\rm P(E)=\frac{n(E)}{n(S)}\)

Calculation:

Total balls in bag = 4 + 6 = 10 balls

A black ball can be drawn in 4 ways out of 10 possible outcomes.

probability of getting a white ball = P(W) = \( \frac{4}{{10}}\)

\(\frac 2 5\)
