A man takes a step forward with probability 0.4 and backwards with probability 0.6 Find the probability that at the end of eleven steps he is just one step away from the starting point?
1. He takes 6 steps forward and 5 steps backward 2. He takes 5 steps forward and 6 steps backward consider 1: p1 = (11C6)(0.4)^6*(0.6)^5 for 2: p2 = 11C5(0.4)^5*(0.6)^6 total probability = p1 + p2
How is probability related to statistics?
Probability is related to statistics in a direct manner. When one is doing a research for statistics, probability has to be used especially in sampling a small region.
What is it called when you calculate the probability of an event without doing any experiments?
When you calculate the probability of an event without doing any experiments, it is called theoretical probability. It is based on mathematical calculations using known information and assumptions about the event.
What are the steps of simulating discrete probability diustributions write the general algorithm?

What is the experimental probability of rolling a 3?
The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling a 3 is 1 in 6, or about 0.1667, but the experimental probability changes every time you run the experiment
