<u>Corrected Question</u>
The Venn diagram shows three types of numbers: odd (O), even (E), and prime (P). Which is represented by Ø?
(A) O ⋃ P (B)E ∩ P (C)O ⋃ E (D)E ∩ O
Answer:
(D) E ∩ O
Step-by-step explanation:
The Venn diagram is reproduced and attached below.
In the Venn diagram, the sets of Odd(O) and Even(E) numbers are disjoint, i.e. there is no intersection.
We can also say the intersection of sets O and E is the empty set.
Therefore: E ∩ O is represented by the empty set Ø.
Generally speaking, a number cannot be even and odd at the same time.
The correct option is D
Answer:
0.375
Step-by-step explanation:
Listing the factors of 30
1, 2, 3, 5, 6, 10, 15, 30 ← that is 8 factors
There are 3, 2- digit factors, that is 10, 15, 30
Thus the probability of choosing a 2- digit number factor is
= 0.375
