Answer:
3/18
Step-by-step explanation:
Given:
Universal set is all positive integers {1,2,3...}
Set A is the set of all positive <u>ODD</u> integers {1,3,5,7...}
The question asks us to find
, which is the <em>complement of set A</em>. The complement of a set refers to elements NOT in that set. Hence, complement of A should be all the elements NOT in A but in Universal Set, U.
It is clear from the question that set A houses all the odd positive numbers, so complement of A will have all the even positive numbers. Last choice is the correct one.
ANSWER:
"{x|x ∈ U and is an even positive integer}"
Answer:
0.9936 is the probability that the student will fail.
Step-by-step explanation:
We are given the following information:
We treat adult guessing correct answer as a success.
P(guess correct answer) = 0.2
Then the number of correct guesses follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 10
The student needs atleast 6 correct answer to pass the test. We have to calculate the probability that the student will fail.
We have to evaluate:
0.9936 is the probability that the student will fail.
Answer:
-4
Step-by-step explanation:
3(2)^2 - 5(2) - 6 = 12 - 10 - 6 = -4
