three coins are tossed simultaneously..what is the probability for the out comes of two heads n one tail...

• 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

  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.

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

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

• Ans: 1/6
  probability= 1/2*1/2*1/2=1/6
• 13 years agoHelpfull: Yes(0) No(2)
• 3/8
  There are total of 8 outcomes with 3 combination of 2 Head and one tail
• 8 years agoHelpfull: Yes(0) No(0)
• 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
