a coin collector has 10 identical silver coins and 6 identical gold coins. in how many ways can he place these 16 coins in a row if no two gold coins are placed next to each other?
Homework Answers
We need no two gold coins are together hence we placed all silver coins at 1-1 place gap between them.
So, there will be total 11 spaces to fit gold coins
It will be like: _S_S_S_S_S_S_S_S_S_S_
There are total _ shows the place where we can put gold coins
Total favorable ways = C(11, 6) = 
So, total 462 ways are there so that no two gold coins are together.
Please comment if any doubt. Thank you.

Alice has two coins. The probability of Heads for the first coin is 1/4, and the probability of Heads for the second is 3/4. Other than this difference, the coins are indistinguishable. Alice chooses one of the coins at random and sends it to Bob. The random selection used by Alice to pick the coin to send to Bob is such that the first coin has a probability p of being selected. Assume that 0<p<1. Bob tries to guess which...
