Answer with Step-by-step explanation:
Let
A=Students are female
B=Students major in civil engineering
The probability that a students are female=P(A)=
The probability that a student major in civil engineering=P(B)=
The probability that students both are female=
a.We have to find the probability that a random selected female student major in civil engineering.
We have to find 
Hence, the probability that a randomly selected female student majors in civil engineering=0.24
b.We have to find the probability that a random selected civil engineering major is female.
We have to find 
Hence, the probability that a randomly selected civil engineering major is female=0.63
Answer:
$6000
Step-by-step explanation:
$1200/5years =$240/1yr
$240=4%
:. 1%=$60
Initial investment =$60*100%=$6000
The probability it will rain today is 0.4 and the probability it will rain tomorrow is 0.3. The <span>probability it will rain today or tomorrow is the sum of the probabilities of the rain today and tomorrow minus the probability of the rain in both two days. Hence, the asnwer is 0.4 + 0.3 - 0.2 equal to 0.5. </span>
When shrinking an image, the size of each side is shrunk by the scale factor. However the area is not shrunk by the same factor. Area is a squared measurement (when finding the area of a rectangle we take length x width; two measurements, so a squared answer), so the area will be shrunk by the scale factor squared; in this case the area is shrunk by 3² or 9. This means the new area would be 720/9 or 80 square inches.
