"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

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
