A certain virus infects one in every 2000 people. A test used to detect the virus in a person is positive 96% of the time if the person has the virus and 4 of the time if the
person does not have the virus. Let A be the event the person is infected" and B be the
event the person tests positive".
a. Find the probability that a person has the virus given that they have tested
positive, ie, find P(AB),
b. Find the probability that a person does not have the virus given that they test
negative, i. e. find P(not Anot B).

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
