Solution :

Here we can use the Binomial distribution, as there are only two possible outcomes.

The given data:

n = 150

q = 98%

  = 0.98

p = probability of not finding relief = 1 - 0.98

                                                         = 0.02

A). The number of the individuals who do not find any relief from sinusitis is  :

E(x) = np

      = 150 x 0.02

      = 3

B). The uncertainty of my estimate is = $\sqrt{npq}$

                                                              $=\sqrt{150 \times 0.02 \times 0.98}$

                                                              = 1.716
