Answer:
The probability that the selected person is a woman engineering major is 0.0396.
Step-by-step explanation:
The proportion of students at the university who are women is 0.42.
<em>P (W) = 0.42</em>
The proportion of students at the university who are engineering majors is 0.18.
<em>P (E) = 0.18</em>
The proportion of engineering majors that are women is 0.22.
<em>P (W|E) = 0.22</em>
The proportion of students at the university that are woman and engineering major is:
Thus, the probability that the selected person is a woman engineering major is 0.0396.
Answer:
Option b) 0.161
Step-by-step explanation:
We are given the following information:
We treat correct as a success.
P(Correct Answer) = = 0.2
Then the number of questions 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 = 11
We have to evaluate:
P(answer at least 4 questions correctly)
Thus, 0.161 is the probability that Richard will answer at least 4 questions correctly.
Option b) 0.161
