- \(\dfrac{3}{5}\)
- \(\dfrac{1}{5}\)
- \(\dfrac{1}{2}\)
- \(\dfrac{2}{5}\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Total number of balls.
\[4 + 6 = 10\] Step 2: Favourable outcomes.
Red balls \(= 4\).
Step 3: Probability.
\[\dfrac{4}{10} = \boxed{\dfrac{2}{5}}\]
\[4 + 6 = 10\] Step 2: Favourable outcomes.
Red balls \(= 4\).
Step 3: Probability.
\[\dfrac{4}{10} = \boxed{\dfrac{2}{5}}\]
