two coins are flipped & atleast one of the output is known to be head,wat is d probability that both outcomes are head.

• as it is fixed that one of the outcome is head.
  sample space for flipping of two coins = {(H,T),(T,H),(H,H)}
  P(TWO HEADS) = 1/3

• out comes occur={(h,h),(h,t),(t,h),(t,t)}
  =4.
  at least one of the output head=3.
  p=3/4.

• 1/2
  two coins are flipped & atleast one of the output is known to be head,
  probability of getting head on other coin =1/2.
  probability that both outcomes are head = 1*1/2=1/2.

• Two coins are flipped.
  One is shown head. So here we already got head. The probability is = 1.
  Another one is either head or tail. So probability of getting head is =1/2.
  So total probability is =1+1/2
  =3/2.

• as it is fixed that one of the outcome is head.
  then we have already fixed that either we have sample space{(h,t),(h,h)}or{(t,h),(h,h)}
  so, p(two heads)=1/2

• 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

• 1st coin 2nd coin
  HEAD HEAD
  HEAD TAIL
  TAIL HEAD
  TAIL TAIL
  
  In question given that output is HEAD...so there are only 3 ways,
  
  4th way TAIL-TAIL is not taken
  
  so the P ( BOTH HEADS ) = 1/3

• sample space for two coins are flipped is S = {HH, HT, TH, TT}
  one of the output is known to be head therefore new sample space becomes S1 = {HT, HH, TH}
  now getting the both heads probability is 1/3

• 1/2, according to the question it is known that one coin should show head but second one is doubt so the probability to show head is for one coin is 1/2, if it happen the two coins shows head

• S={HH,HT,TH,TT}
  E={HH}
  P(E)=1/4
