. coins of 1,2, 5 rupees are tossed , what is the probability of getting a head on 1,tail on 2 and head on 5 rupee.
(a) ½ (b) ¼ (c) 1/8 (d) 1/16

• ans : 1/8
  
  any coin probability of getting H or T is 1/2
  so 1/2 *1/2 * 1/2 = 1/8

• probablity of getting head on re 1= 1/2
  probablity of getting tail on rs 2= 1/2
  probablity of getting head on rs 5= 1/2
  so net probablity= 1/2*1/2*1/2=1/8

• frns hw cme ans vill b 1/8....sample space 4r tossing 3 coins is 8 na...nd den probabity 4r head on 1rupee is 1/2 ndtail on 2rupees is 1/2 nd head 5rupees is also 1/2...now net prababity shud b (1/2*1/2*1/2)/8 i.e 1 na?

• SAMPLE SPACE FOR TOSSING 3 COINS IS 8
  HEAD ON 1ST COIN, TAIL ON 2ND COIN,HEAD ON 3RD THAT IS (H,T,H) WHICH IS 1 SPACE
  SO PROBABILITY IS 1/8 ...

• for the outcome of 3 coins, we will have 2^3 possibility(coins are in the order 1,2,5):
  HHH,HHT,HTH,HTT,THH,THT,TTH,TTT.
  FROM THE ABOVE , only 3rd condition follows the question.
  so , ans:1/8

• guys mutually exclusive events... so 1/2 is the answer i think...

• 1/8
  Because 8 possibilities are there and only 1 meets the condition.

• probability of getting H(1) = 1/2
  probability of getting T(2) = 1/2
  probability of getting H(5) = 1/2
  Hence total Probability = 1/2 * 1/2 * 1/2
  = 1/8

• sample space =8
  the condtion according to question is ......HEAD TAIL HEAD (HTH)
  number of event =1
  probability=event/sample space=1/8,..............:)

• (1/2)*(1/2)*(1/2)=1/8
• 7 years agoHelpfull: Yes(0) No(0)
• ans:1/8
  because any coin probability of getting H or T IS 1/2
  SO COIN OF 1 rupees probability is 1/2
  coin of 2 rupees probability is 1/2
  coin of 5 rupees probability is 1/2
  then total probability is 1/2*1/2*1/2=1/8

• the solution is 1/8
  i.e; 1/2*1/2*1/2=1/8
