Once of the four persons John, Rita, Aslam or Gurpreet will be promoted next month. Consequently the sample space consists of four elementary outocomes S={John promoted, Rita promoted, Aslam promoted, Gurpreet promoted}. You are told that the chances of John's promotion is same as that of Gurpreet Rita's chances of promotion are twice as likely as John's Aslam's chances are four times that of John.
(i) Determine
P (John promoted),
P (Rita promoted),
P (Aslam promoted),
P (Gurpreet promoted).
If A= {John promoted or Gurpreet promoted}, find P (A)

Explanation

To solve the problem, we need to determine the probabilities of promotion for each of the four individuals: John, Rita, Aslam, and Gurpreet. Let's break down the solution step by step.

### Step 1: Define the probabilities
Let:
- \( P(J) \) = Probability of John being promoted
- \( P(R) \) = Probability of Rita being promoted
- \( P(A) \) = Probability of Aslam being promoted
- \( P(G) \) = Probability of Gurpreet being promoted
