MCQ
A month is selected at random from a year. The probability that it is May or July is
  • A
    $\frac{1}{12}$
  • ✓
    $\frac{1}{6}$
  • C
    $\frac{3}{4}$
  • D
    $\frac{1}{3}$
✓

Answer

Correct option: B.
$\frac{1}{6}$
(b):Number of months in a year $=12$
So, total number of possible outcomes $=12$
Favourable outcomes are May or July i.e., 2
$\therefore \quad$ Required probability $=\frac{2}{12}=\frac{1}{6}$
