There are 2 shelves. One shelf has 5 Physics and 3 Bilogy books and other has 4 Physics and 2 Biology books. Then probability of drawing a Physics book is

Options

  1. A1 2
  2. B31 48
  3. C9 14
  4. D9 38

Correct answer

B. 31 48

Step-by-step solution

The required probability =P (S₁ ) P (P / S₁ )+P (S₂ ) P (P / S₂ )= 1 2 5 8 + 1 2 4 6 = 31 48
