Question

Three Coins are tossed, find the probability that two heads and one tail are obtained?

Answer 1

Answer:

as three coins are tossed so outcome will be 9

the probability of two heads and one tails is

1st coin is head, 2nd coin is head, 3rd coin is tails

1st coin is tails, 2nd coin is head, 3rd coin is head

1st coin is head, 2nd coin is tail, 3rd coin is head

total out come is 9

desired outcome is 3

so probability is 3/9= 1/3

Answer 2

Answer:

3/8

Step-by-step explanation:

Three coins are tossed

So the sample space is

TTT,

TTH, THT, HTT,

THH, HTH, HHT,

HHH.

NO. OF TIMES TWO HEADS AND ONE HEAD OCCUR =3

TOTAL NUMBER OF OUTCOMES =8

P(Two heads and one tail occurred) =(no. Of times two heads and one tail ocgur) / (total number of outcomes )

P = 3/8
