Answer:
6032
Step-by-step explanation:
7 out of 13 are accepted, so in total 0.538 % is accepted.
So 3248 / 0.538 = 6032 students applied.
Part (a)
P(A) = 0.5
P(B) = 0.4
P(B/A) = 0.6
P(A and B) = P(A)*P(B/A)
P(A and B) = 0.5*0.6
P(A and B) = 0.3
<h3>Answer: 0.3</h3>
==========================================
Part (b)
We'll use the result from part (a)
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.5 + 0.4 - 0.3
P(A or B) = 0.6
<h3>Answer: 0.6</h3>
===========================================
Part (c)
A and B are not independent since P(B) does not equal P(B/A). The fact that event A happens changes the probability P(B). Recall that P(B/A) means "probability P(B) based on event A already happened". A and B are independent if P(B) = P(B/A).
Events A and B are not mutually exclusive since P(A or B) is not zero.
<h3>Answer: Neither</h3>
Answer:
length = 6
width = 6
height = 6
Step-by-step explanation:
Area of the square = 6 * 6
Area of the square = 36
The perimeter = 6 + 6
The perimeter = 12
so 36 is 3 times bigger than 12
The correct answer is B.)
