"Police report that 78% of drivers are given a breath test, 36% a blood test, and 22% both tests. Find Upper P (breath test|blood test). Choose the correct answer below. A. 0.22/0.36B. 0.78/1.00 C. 0.14/0.36 D. 0.22/0.78"

A.

Step-by-step explanation:

Conditional probability:-

If E and F are two events in a sample space S and P( F) ≠ 0 , then the probability of 'F' after the event 'E' has occurred, is called the conditional probability of the event of F given E and is denoted by

P(E/F) =

"Police report that 78% of drivers are given a breath test

36% a blood test and 22% both tests

let 'B' be the event of blood test and 'Br' be the event of breath test

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
