# Question #e49ee

##### 2 Answers

p = 0.3, n= 12, let x = The number of accidents to 18 year old drivers within one year of taking license;

Required Prob. = 0.49071.

#### Explanation:

X follows binomial distribution with n= 12 and p = 0.3

general p.d.f. is f ( x) =

Required Pr{ X

= Pr {X = 0} + Pr{X = 1} + Pr { X = 2} + Pr {X = 3} =

= 0.01384 + 0.07118 + 0. 16779 + 0.23790 =0.49071

Refer explanation section

#### Explanation:

Following Binomial Distribution the answer is

Following Poisson Distribution the answer is

Following Normal Distribution the answer is

I am sorry I have wrongly totaled the probability values.

I have redone the problem using the three distributions.

I have enclosed my work in a pdf file form.

I am unable to get the answer that you have given 0.3327.

May I know in which area the problem appears in your book.
