Family 6
Continuous (exp / pdf) + binomial
These 3 topics share one solution. Spot the family, apply the method — same trick, different story.
How to spot this family
- Radio tube, given pdf → integrate：The problem hands you a piecewise pdf directly (it does NOT say "exponential distribution"!) · Common form for · b) Again a binomial with given p, asking for at most k
- Mobile phone, exponential → binomial："time ... having the Exponential distribution with mean m" · b) "a new model has probability p ... we have n of these" → switch to binomial
- Surveillance camera, exponential → binomial："time ... Exponential distribution with mean 50 days" · b) 16 new cameras, given p, at least 8
