The probability that a person chosen at random is left handed (in hand writing) is 0.1 . Then the probability that in a group of 10 people there is a left handed person is

Options

  1. A(0.9)^9
  2. B(0.9)^8
  3. C(0.9)^6
  4. D0.9

Correct answer

A. (0.9)^9

Step-by-step solution

p =0.1 ; q =0.9 The probability of left handed person in a group of 10 people is: aligned & P = ¹⁰ C ₁ p ^1 q ¹⁰⁻¹=10 0.1 (0.9)^9 & P =(0.9)^9 aligned
