An unbiased coin is tossed n times. Let X denote the number of times head occurs. If P(X=4), P(X=5) and P(X=6) are in A.P, then the value of n can be

Calculate the probability that “heads” will come up 60 times if an unbiased coin is tossed 100 times. Exercise 16.3 Find the mean and the standard deviation for the distribution of “heads” coins in the case of 10 throws of an unbiased coin. Find the probability that a single toss will...
For example, if an unbiased coin (p=0.5) is tossed n times, the probability of any particular outcome is (0.5)x(1-0.5)n-x=(0.5)n=1/2n; in this case all 2n outcomes are equally likely. It is often the case that the exact sequence of successes and failures is not important ...
Probabilityis the likelihood of an event in a Random experiment. For instance, if a coin is tossed, the chance of getting a head is 50% so, probability is 0.5. Sample Space: It is the set of all possible outcomes of a Random Experiment.Favourable Outcomes: The set of outcomes we are ...

coin tossed into the air will land with its head side or tail side up Performing the same experiment over a long period of time would yield data sufficient to indi- cate that on the average it is equally likely that a head or tail will turn up Studying this average behavior of events ...
“Philosophy molds and shapes the mind, gives order to life and discipline to action, shows what to do and what not to do. It sits at the helm and steers a course for us who are tossed in waves of uncertainty. Without it, there is no life that is not full of anxiety and cares.”...
