Answer 1

Answer:

Option B (a+b-2ab)

Answer 2

Given the probability that Soumya will get married within 365 days is 'a' and the probability that her colleague Alma getting married within 365 days is 'b'.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Now, P(A) = a, P(B) = b.

We need to find $P(A \cup B)$

We know that $P(A \cup B) = P(A)+P(B)-2P(A)P(B)$

We substitute the values of P(A) and P(B) and we get

$P(A \cup B) = a+b-2ab$

Therefore, the correct option is option B.
