Question 1161818
.
<pre>

(a)  P = P(1) = {{{C[10]^1*0.01^1*0.99^9}}} = {{{10*0.01*0.99^9}}} = 0.091352.    <U>ANSWER</U>


(b)  P = the complement to the probability that no one of 10 has HIV and AIDS = 

          1 - {{{0.99^10}}} = 0.095618.    <U>ANSWER</U>


(c)  P = P(0) + P(1) = {{{0.99^10}}} + the value of P(1) from (a) = 

                       {{{0.99^10}}} + {{{10*0.01*0.99^9}}} = 0.095618 + 0.091352 = 0.995734.    <U>ANSWER</U>


(d)  The average is 1%, which is clear and follows from the condition without any calculations.


(e)  P = P(2) = {{{C[10]^2*0.01^2*0.99^8}}} = {{{((10*9)/2)*0.01^2*0.99^8}}} = 0.00452.    <U>ANSWER</U>

The correct writing for this disease is AIDS, in English.


It is not "ADIS", as you often write in your post.
