The probability that the person who undergoes certain operation will survive is 0 2 . If 5 patients undergo similar operations, then the probability that exactly four will survive is

Options

  1. A0.0042
  2. B0.0084
  3. C0 0032
  4. D0 0064

Correct answer

D. 0 0064

Step-by-step solution

Since there are 5 patients, n = 5 P(Pprobability of patient survive) = 0.2 aligned & p-0.2 q=1-p=1-0.2=08 & P(x=4)= 5 4 (0.2)⁴(0.8)¹=5 0.0016 0.8=0.0064 aligned
