Answer:
The probability that a randomly selected American Airlines flight does not arrive on time is 0.197.
Step-by-step explanation:
The probability of the complement of an event <em>E</em> is the probability of it not happening.
That is,
It is provided that the probability of American Airlines flights arriving on time (<em>X</em>) is,
P(X) = 0.803
Then the event of American Airlines flights not arriving on time is the complement of the event <em>X</em>.
Compute the probability of the complement of event <em>X</em> as follows:
Thus, the probability that a randomly selected American Airlines flight does not arrive on time is 0.197.
Answer:
He now has 6 apples.
Step-by-step explanation:
If Steve has eaten 2 apples, but had 8 before, he would have 6 left because he is taking away 2 apples from 8.
8 - 2 = 6
Answer:
99
Step-by-step explanation:
64
+ 35
= 99
Answer: 0.9996
Step-by-step explanation:
Given : The body temperatures of adults are normally distributed with a mean of 98.6° F and a standard deviation of 0.60° F.
Sample size : n=25
Let x be the random variable that represents the body temperatures of adults.
z-score :
For x= 99° F
Now, the probability that their mean body temperature is less than 99° F will be :-
Hence, the probability that their mean body temperature is less than 99° F = 0.9996
