What is the probability of a man taking a step forward?

What is the probability of a man taking a step forward?

A man takes a step forward with probability 0.4 and backward with probability 0.6. The probability that at the end of eleven steps he is one step away from starting point is As 0.4+0.6 = 1, the man either takes a step forward or a step backward. Let a step forward be a success and a step backward be a failure.

How many steps forward and one step backward?

Let us denote a forward step by and a backward step by . There are only two ways to take 11 steps and end up one step from the starting point: , or any permutation of this. The final position is one step ahead of the starting point. , or any permutation of this. The final position is one step behind the starting point. Condition 1.

How many steps does a man have to take?

He has to move just one step away from the starting point, in 11 steps. he has to have one Forward, one Backward and last one be any of the two. Then he has to have Two Forward, Two Backward and last one be any of the two. Then he has to have Three Forward, Three Backward and last one be any of the two. Hope you got the logic! So here..

What is the probability of six F’s in a row?

Condition 1. The probability of six F ’s in a row followed by five B ’s in a row is ( 0.4) 6 ( 0.6) 5. Yes, thousands of people all over the world know how to solve this problem. One of them is me. FFFFFFBBBBB, or any permutation of this. The final position is one step ahead of the starting point. BBBBBBFFFFF, or any permutation of this.
