There are 8 boys and 4 girls in a lift. What is the probability that the first person who steps out of the lift will be a boy?
- \(\frac{1}{6}\)
- \(\frac{1}{4}\)
-
\(\frac{2}{3}\)
- \(\frac{1}{2}\)
The correct answer is: C
Explanation
Total number of people in the lift = 8 boys + 4 girls
= 12 people
probability that a boy comes out = \(\frac{8}{12}\) = \(\frac{2}{3}\)
