What is the probability that it also rained that day answer 0.3
Answer:
Step-by-step explanation:
3b + 2f = 17
2b + 4f = 18
-6b - 4f = -34
6b + 12f = 54
8f = 20
f = $2.50 fries
3b + 2(2.5) = 17
3b + 5 = 17
3b = 12
b = $4 burger
The number is -9
Step-by-step explanation:

Answer and explanation:
Given : A driving exam consists of 29 multiple-choice questions. Each of the 29 answers is either right or wrong. Suppose the probability that a student makes fewer than 6 mistakes on the exam is 0.26 and that the probability that a student makes from 6 to 20 (inclusive) mistakes is 0.53.
Let X be the number of mistake


To find : The probability of each of the following outcomes.
a) A student makes more than 20 mistakes
i.e. 





b. A student makes 6 or more mistakes
i.e. 


c. A student makes at most 20 mistakes
i.e. 
Using 'a' part 


d. Which two of these three events are complementary?
The complement of an event happening is the exact opposite: the probability of it not happening.
According to definition,
Option a and c are complementary events.
