Answer:
Correct option: (B) 1.495%.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = the test is positive.
<em>A</em> = a person with the dominant allele
The information given are:
According to the law of total probability the probability of an event <em>A, </em>conditional upon the occurrence of another event <em>B</em> is:
Use this law to compute the probability of person having a positive result as follows:
The percentage of positive result is: 0.01495 × 100 = 1.495%.
Thus, the percentage of the population will give a positive test is 1.495%.
There is 20% decrease in the number of members.
Step-by-step explanation:
Given,
Members last year = Old value = 30
Members this year = New year = 24
Change = New value - Old value
Change = 24 - 30
Change = -6
The negative sign indicates the decrease.
Decrease percent =
Decrease percent =
Decrease percent =
Decrease percent = 20%
There is 20% decrease in the number of members.
