a)
P(have symptom A)=P(have disease D1 and symptom A)+P(have disease D2 and symptom A)
=0.06*0.4+0.02*0.8=0.04
b)P(Carries D1 given have symptom A)==P(have disease D1 and symptom A)/P(have symptom A)
=0.06*0.4/0.04=0.6
D, and D2 cause sympton A with probabilities 04 and 0.8 respectively. Suppose 6% of a...
in a region, there is a 0.8 probability chance that a randomly selected person of the population has brown eyes. assume 12 people are randomly selected. complete parts (a) through (d) below. find the probability that all of the 12 selected people have brown eyes is? find the probability that exactly 11 people have brown eyes? the probability that the number of selected people that have brown eyes is 10 or more is? if 12 people are randomly selected, is...
6. Of all people in one population, 21% have high blood pressure and 36% are overweight. In addition, 42% of people who are overweight also have high blood pressure. Let H represent the event that a person has high blood pressure, and O represent the event that a person is overweight. In each part of this question, you must first express each probability in terms of the events Hand O and justify any computation through the use of a formula....
I need help with Question 2, Question 3, Question 4,
and Question 5 please.
Question . A die was rolled twice、The first time it landed on a number that we will call "x" The second tme landed on a number that we will call "y" We will symbolize some events as follows: x is odd. xis a prime. y is odd. y is a prime. A: B: C: D: Express the following probabilities using the notation "p(.。.)". For example, the...
These are all part of the same question if you cant answer them
all dont asnwer at all. I will thumbsdown. thanks
Let y denote the number of broken eggs in a randomly selected carton of one dozen eggs. Suppose that the probability distribution of v is as follows У01234 p(y) 0.64 0.20 0.11 0.04? (a) Only y values of 0, 1, 2, 3, and 4 have positive probabilities. What is p(4)? (Hint: Consider the properties of a discrete probability...

THE WAR ON ALLERGIES SUPPOSE THAT 54.3 PERCENT of your country's population had cancer. That figure might set off a nationwide panic-a search for something wrong with people's diet, the environment, activity levels. In fact, that's the percentage of Americans who show a positive skin response to one or more allergens. A1 5 B The manifestations' of allergy-sneezing, itching, rashes-are signs of an une system running amok,2 attacking foreign invaders-allergens- that mean no harm. Allergens include pollen, dust mites, mold,...
