The value of the set operation A U ∅ is {3, 4, 5, 6}
<h3>How to evaluate the set operation?</h3>
The elements of the sets are given as:
U = {1, 2, 3, 4, 5, 6}
A = {3, 4, 5, 6}
To calculate the set A U ∅, we use the following illustration
A U ∅ = set A combined with an empty set
This gives
A U ∅ = {3, 4, 5, 6} combined with an empty set
This gives
A U ∅ = {3, 4, 5, 6}
Hence, the value of the set operation A U ∅ is {3, 4, 5, 6}

Answer:
Step-by-step explanation:
let the number be x %
according to the question the equation is
x% of 15=45
x/100*15=45
15x=45*100
x=4500/15
x=300
therefore x=300%
Answer:
See below in bold,.
Step-by-step explanation:
There are 30-17 = 13 boys in the class.
a. Prob(First is a boy ) = 13/30 and Prob( second is a boy = 12/29).
As these 2 events are independent:
Prob( 2 boys being picked) = 13/30 * 12/29 = 26/145 or 0.179 to the nearest thousandth.
b. By a similar method to a:
Prob ( 2 girls being picked) = 17/30 * 16/29 = 136/435 = 0.313 to the nearest thousandth.
c. Prob (First student is a boy and second is a girl) = 13/30 * 17/29 = 221/870.
Prob ( first student is a girl and second is a boy) = 17/30 * 13/29 = 221/870
These 2 events are not independent so they are added:
Prob( one of the students is a boy) = 2 (221/870 = 221/435 = 0.508 to the nearest thousandth.
1/10 has the greatest value
