alleryStart learning →A bag has 3 red and 2 blue balls. The probability of drawing a red ball at random is
A$\dfrac35$
B$\dfrac25$
C$\dfrac13$
D$\dfrac12$
Answer & Solution
Correct answer: A. $\dfrac35$
1. Total balls = 3 + 2 = 5; favourable (red) = 3.
2. $P(\text{red}) = \dfrac{3}{5}$.
3. So the probability is $\dfrac35$.
