Answer:80students
Step-by-step explanation:
Using set notation concept,
n(U) be the total number of student = 200
n(AnS') be those that earned Bachelor in Art only= 120
n(A'nS) be those that earned Bachelor in Science only= 40
n(AnS) be students that earned both degrees.
Using the formulae below to calculate n(AnS) first;
n(AuS)=n(A'nS)+ n(AnS)+n(AnS')
200=40+n(AnS)+120
200=160+n(AnS)
n(AnS)=40
This shows that 40students earned bachelor in both degrees
Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.
NB: A' means complement of A(A not included)
'n' denote intersection and 'u' denote union.
Answer:
2/3
Explanation:

<u>carpenters</u>: 4 carpenters
<h3>probability = favourable outcomes/total possible outcomes</h3>
probability = 4/6 ≈ 2/3

Answer:
a = -3
Step-by-step explanation:
−40 + 10a = -70
10a = -70 + 40
10a = -30
a = -30/10
a = -3
