It is observed that 30 % of the students appearing for a certain entrance test are science students. If 5 students are randomly selected from this group,the probability of having 2 science students among these students is

Options

  1. A0.3087
  2. B0.2547
  3. C0.1087
  4. D0.3437

Correct answer

A. 0.3087

Step-by-step solution

The required probability = ^5 C₂ ( 30 100 )^2 ( 70 100 )^3 aligned & =10 3 10 3 10 7 10 7 10 7 10 & = 3087 10000 =0.3087 aligned
