Step-by-step explanation:
a) To complete the Venn diagram based on the given
information:
-E= (odd numbers less than 30) =1,3, 5, .., 29}
-A={9, 15, 17, 19}
- B= (5, 15, 25)
-C= (9, 15, 21, 27
We can start by placing the numbers in their respective sets on
the Venn diagram.
-A contains 9, 15, 17, and 19.
- B contains 5, 15, and 25.
-C contains 9, 15, 21, and 27.
Now, to find the intersection between sets A and B (An B), we
need to identify the numbers that are common to both A and B.
In this case, the number 15 is the only number that belongs to
both sets A and B.
b) The probability that a number chosen at random from set E is
a member of A nB can be calculated by the formula:
P(ANB) =E
|AnB|
Given that the only number in the intersection of A and B is 15,
and the total numbers in set E (odd numbers less than 30) are
15, the probability is:
P(AN B) =t
Therefore, the probability that the number chosen at random
from set E is a member of A n B is 1/15.
