The mean and the variance of a binomial distribution are 4 and 2 respectively. Then the probability of 2 successes is:

Take any positive whole number not greater than 50.If the number is even, divide it by 2.If the number is odd,multiply it by 3,and add 1 to the

result. Apply the same method to the resulting numbers until you finally arrive at the number 1.shown below is the chain of numbers that results from

this method if you begin with 15.

15->46->23->70->35->106->53->160->80->40->20->10->5->16->8->4->2->1
