Answer:
1.U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}
2.U={1,2,3,4}
A={1,2}
B={2,3}
C={4}
Step-by-step explanation:
We are given that 
and 
are different sets
1.We have to construct a universe set U and non empty sets A,B and C so that above set in fact the same
Suppose U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}
{2,3,4,5}
={2}
{2,3,4,5}={2}
={2}
={2}
Hence, 
2.We have to construct a universe set U and non empty sets A,B and C so that above sets are in fact different
Suppose U={1,2,3,4}
A={1,2}
B={2,3}
C={4}
={2,3,4}
={1,2}
={1,2}
={1,2} {2,3,4}={2}
Hence, 
Answer:
$106.25
Step-by-step explanation:
earns in 1 hour = $8.50
earns in 12.5 hr= $8.50*12.5= $106.25
Let: hypotenuse = a , known leg = b , unknown leg = c
According to Pythagoras' Theorem:
c =
c = 3.74 inches
∴ the length of the hypotenuse to 1d.p. ≈ 3.74 inches
Using it's concept, the desired probability is:
P(Female|Junior) = 75%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 8 Junior Students, out of which 6 are Female, hence the probability is:
P(Female|Junior) = 6/8 = 0.75 = 75%.
