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

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 ...
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 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 looking for in a Random Experiment Probability = (Number of ...
Probability is 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 ar...
The probability of A occurring is .3 and the probability of B occurring is .5. What is the probability of both A and B occurring if A and B are mutually exclusive? What is the probability that either A or B but not both will occu...
Man finds himself tossed and turned upon the waves of strife; Struggles to find his place in this bustle of confusion called life. Holding fast the reins of his passion, until he is forced to let go; Fortune’s wheel presses the many into the crude rocks below. ...
