3/8.

Possible outcomes are
TTT
TTH
THT
THH
HTT
HTH
HHT
HHH

Out of 8 combinations, 3 are required combinations.

so prob =3/8

Pls check this qn. How many 4 or 5 digit numbers can be formed by using 0, 1, 3, 5, 8. Repetition is not allowed. None of the given options is correct. No. of 4 digit nos that can be formed by using 0, 1, 3, 5, 8.( Repetition is not allowed.)=4*4*3*2=96 No. of 5 digit nos that can be formed by using 0, 1, 3, 5, 8.( Repetition is not allowed.)=4*4*3*2*1=96 Total No. of 4 digit or 5 digit nos that can be formed by using 0, 1, 3, 5, 8.( Repetition is not allowed.)=96+96=192

3/8
ie. when 3 coins are tossed the total no.of solutions are 8 = ( 2 power 3)
2 heads, 1 tail is possible in 3c2 or 3c1 ways = 3

Is this solution Helpfull? Yes (3) | No

Out of 8 combinations, 3 are required combinations.

so prob =3/8..its easy

since there are 3 coins so sample space will be={HHH,HHT,HTH,THH,HTT,TTH,THT,TTT}.
out of all these favourable sample spaces are={HHT,HTH,THH}.
so required probability=favourable no. of events/total no. of events=3/8.

KALPANA G  (13 years ago)

posibilitiex are HHT HTH THH.
So, required probability is 3

Is this solution Helpfull? Yes (1) | No (6)  

Pinaki Ninad Kulkarni  (13 years ago)

Total outcomes=2*2*2=8. Total favourable outcomes with exactly one tail and 2 heads are 3. Hence answer is 3/8

Is this solution Helpfull? Yes | No (2)  

Garima Mishra  (13 years ago)

Ans: 1/6
probability= 1/2*1/2*1/2=1/6

Is this solution Helpfull? Yes | No (2)  

Hemant Kumar  (7 years ago)

3/8
There are total of 8 outcomes with 3 combination of 2 Head and one tail

Is this solution Helpfull? Yes | No   

kavibharathi  (7 years ago)

by tossing three coins simultaneously the total probability will be 8
HHH
HHT
HTH
THH
TTT
TTH
THT
HTT
outcomes of two head and one tail means :3
so the probability is 3/8
