Atleast 8 Tails in 10 Coin Tosses
The ratio of successful events A = 56 to the total number of possible combinations of a sample space S = 1024 is the probability of 8 tails in 10 coin tosses. Users may refer the below solved example work with steps to learn how to find what is the probability of getting at-least 8 tails, if a coin is tossed ten times or 10 coins tossed together. Users may refer this tree diagram to learn how to find all the possible combinations of sample space for flipping a coin one, two, three or four times.
Solution
Step by step workout
step 1 Find the total possible events of sample space S
S = {HHHHHHHHHH, HHHHHHHHHT, HHHHHHHHTH, HHHHHHHHTT, HHHHHHHTHH, HHHHHHHTHT, HHHHHHHTTH, HHHHHHHTTT, HHHHHHTHHH, HHHHHHTHHT, . . . . . . ,TTTTTTTHTT, TTTTTTTTHH, TTTTTTTTHT, TTTTTTTTTH, TTTTTTTTTT}
S = 1024
step 2 Find the expected or successful events A
A = {HHTTTTTTTT, HTHTTTTTTT, HTTHTTTTTT, HTTTHTTTTT, HTTTTHTTTT, HTTTTTHTTT, HTTTTTTHTT, HTTTTTTTHT, HTTTTTTTTH, HTTTTTTTTT, THHTTTTTTT, THTHTTTTTT, THTTHTTTTT, THTTTHTTTT, THTTTTHTTT, THTTTTTHTT, THTTTTTTHT, THTTTTTTTH, THTTTTTTTT, TTHHTTTTTT, TTHTHTTTTT, TTHTTHTTTT, TTHTTTHTTT, TTHTTTTHTT, TTHTTTTTHT, TTHTTTTTTH, TTHTTTTTTT, TTTHHTTTTT, TTTHTHTTTT, TTTHTTHTTT, TTTHTTTHTT, TTTHTTTTHT, TTTHTTTTTH, TTTHTTTTTT, TTTTHHTTTT, TTTTHTHTTT, TTTTHTTHTT, TTTTHTTTHT, TTTTHTTTTH, TTTTHTTTTT, TTTTTHHTTT, TTTTTHTHTT, TTTTTHTTHT, TTTTTHTTTH, TTTTTHTTTT, TTTTTTHHTT, TTTTTTHTHT, TTTTTTHTTH, TTTTTTHTTT, TTTTTTTHHT, TTTTTTTHTH, TTTTTTTHTT, TTTTTTTTHH, TTTTTTTTHT, TTTTTTTTTH, TTTTTTTTTT}
A = 56
step 3 Find the probability
P(A) = Successful Events/Total Events of Sample Space
= 56/1024
= 0.05
P(A) = 0.05
0.05 is the probability of getting 8 Tails in 10 tosses.
