MCQ
There are $8$ defective items in a sample of $24$ items. One item is drawn at random. The probability that it is a non $-$ defective item is:
  • A
    $1$
  • ✓
    $\frac{2}{4}$
  • C
    $\frac{1}{2}$
  • D
    $\frac{1}{3}$
✓

Answer

Correct option: B.
$\frac{2}{4}$
Number of Non $-$ defective items $= 24 - 8 = 16$
Number of possible outcomes $= 16$
Number of Total outcomes $= 24$
Probability of getting a Non $-$ defective item $=\frac{16}{24}=\frac{2}{4}$
