Question

16. Á candidate is selected for interview for three posts. For the
first post there are 3 candidates, for the second there are 4
and for the third there are 2. What are the chances of his
getting at least one post?​

Answer 1

Answer:3/4

Step-by-step explanation:

Let A, B and C denote the events that the candidate gets the first , second and third post respectively.

Therefore , P(A) =1-P(A)=2/3

P(B)=1/4

P(C)=1/2

Now , probability that candidate will get at least one post is P(A∪B∪C)

=1-P(AUBUC)

1-P(A)P(B)P(C) (since events A,B,C are independent , A,B,C are also independent).

1-2/3*3/4*1/2=3/4...
