Combinatorics & Probability
A rumor is spread randomly among a group of 10 people by successively having one person call someone, who calls someone, and so on. A person can pass the rumor on to anyone except the individual who just called. (a) By how many different paths can a rumor ... in $N$ calls? (c) What is the probability that if $A$ starts the rumor, then $A$ receives the third calls?

#self doubt
The number of bit strings of length 8 that will either start with 1 or end with 00 is? (https://gateoverflow.in/15898/isro2014-19) In the ‘either or’ case we will include the ‘and’ case also? means: 1 string starting with 1 2 stating ending with 00 3 strings start with 1 and end with 00 all above cases will be included in either or case or only 1,2 will be included?
