Master Yoda selected n candidates to get Jedi training. Each candidate may or may not accept (with probability p of acceptance) to get the training to be a youngling. The probability of completing the training is s for each youngling (the ones who accepted to offer). Let X represent the number of younglings who completes the training, whereas Y denote the number of younglings who does not complete the training (i.e. the ones accepted the offer yet could not complete the training).

(a) Explicitly state the distribution of X including parameters. A clear verbal explanation will be suffice.

(b) Find the joint pmf of X and Y .

Okay ..... Please tell us the definitions of:

  • state the distribution

  • the joint pmf of relevant out-put variables
These should be available in your textbook/class-notes.

Please come back and tell us - what you found....
 
If you have no idea how to even start then you need to talk to your teacher about this. The last thing you want is to turn in homework done by someone else and fool you teacher into thinking you do know it.
