X1 and X2 represent number of occurrences of event A and 8 that follow Poisson distribution with mean rate λ1 and λ2 , If Y1 and Y2 are inter-occurrence times of event A and B, then min(Y1, Y2 ) follows
1. Exponential distribution with mean rate min (λ1, λ2 )
2. Exponential distribution with mean rate (λ1 + λ2 )
3. Poisson distribution with mean rate (λ1 - λ2 )
4. Poisson distribution with mean rate (λ1 + λ2 )
The correct answer is B
