A coin is tossed 12 times. a) How many different outcomes are possible? b) What is the probability of getting exactly 3 heads? c) What is the probability of getting at least 2 heads? d) What is the probability of getting at most 8 heads?

Expert Solution

From the given information, X: No. Of heads in 12 tosses follows Binomial Distribution with parameters n= 12 and p= 0.5

Hence it's p.m.f. is used to calculate required probabilities.

A coin is tossed three times. An outcome is represented by a string of the sort HTT (meaning a head on the first toss, followed by two tails). The 8 outcomes are listed in the table below. Note that each outcome has the same probability. For each of the three events in the table, check the outcome(s) that are contained in the event. Then, in the last column, enter the probability of the event. Outcomes Probability TTH TTT HHH THT...
