Answer:
0.6154 = 61.54% probability that the student is an undergraduate
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Foreign
Event B: Undergraduate.
There are four times as many undergraduates as graduate students
So 4/5 = 80% are undergraduate students and 1/5 = 20% are graduate students.
Probability the student is foreign:
10% of 80%
25% of 20%. So
Probability that a student is foreign and undergraduate:
10% of 80%. So
What is the probability that the student is an undergraduate?
0.6154 = 61.54% probability that the student is an undergraduate
Answer:
B) 29
Step-by-step explanation:
Given:
AC= 58
Point D and E are the midpoints of side AB and BC Respectively.
Solution:
According to Midpoint theorem which states:
"The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side."
DE=
AC
DE=
Hence length of DE is 29.
