 invernessgangshow.net"s solved instance with equipment to find what is the probability of gaining 1 Head in 3 coin tosses. P(A) = 7/8 = 0.88 for total feasible combinations because that sample an are S = HHH, HHT, HTH, HTT, THH, THT, TTH, TTT & successful events for obtaining at the very least 1 head A = HHH, HHT, HTH, HTT, THH, THT, TTH because that an experiment consists of three independent events.

You are watching: If you flip a coin 3 times what is the probability of getting 1 heads

The over probability the outcomes applicable to the listed below questions too.
Probability the flipping a coin 1 times and getting 3 head in a heat Probability of acquiring 3 head as soon as flipping 1 coins with each other A coin is tossed 1 times, discover the probability that at least 3 are head? If you flip a fair coin 1 times what is the probability the you will get exactly 3 head? A coin is tossed 1 times, what is the probability of getting specifically 3 head?

The ratio of successful occasions A = 7 to the total number of possible combine of a sample an are S = 8 is the probability the 1 head in 3 coin tosses. Users might refer the below solved example work with steps to learn just how to uncover what is the probability of gaining at-least 1 head, if a coin is tossed three times or 3 coins tossed together. Users may refer this tree diagram to learn how to find all the feasible combinations of sample an are for flipping a coin one, two, 3 or 4 times.

SolutionStep by action workoutstep 1 uncover the total feasible events of sample space S S = HHH, HHT, HTH, HTT, THH, THT, TTH, TTT S = 8 step 2 discover the meant or successful events A A = HHH, HHT, HTH, HTT, THH, THT, TTH A = 7 step 3 discover the probability P(A) = successful Events/Total events of Sample space = 7/8 = 0.88 P(A) = 0.88 0.88 is the probability of getting 1 Head in 3 tosses.

The proportion of successful occasions A = 3 come total variety of possible combine of sample space S = 8 is the probability that 1 head in 3 coin tosses. Users might refer the below detailed solved instance with action by step calculation to learn exactly how to discover what is the probability the getting specifically 1 head, if a coin is tossed three times or 3 coins tossed together.
