Unformatted text preview: case that all three get heads or tails, they continue tossing until they reach a decision. Let p be the probability of heads and q =1-p , the probability of tails. Find the probability that they reach a decision in less than n tosses. If p =1/2, what is the minimum number of tosses required to reach a decision with probability 0.95? *If only one child gets a head (or tail), this child is “odd.” 4. Under what conditions is the sum of two independent binominal random variables, with parameters (n,p) and (m,q) respectively, a binomial random variable? Prove your answer....
