find out the probability to get 1Rs coin head, 2Rs coin Tail and 5Rs coin head??
a) 1/2
b) 1/8
c) 1/16
d) None of these

• 1Rs coin head=1/2
  2Rs coin Tail=1/2
  5Rs coin head=1/2
  
  =(1/2)*(1/2)*(1/2)
  =1/8

• ans b) 1/8
  
  reason: getting head of 1rs=1/2
  getting tail of 2rs=1/2
  getting head of 5rs=1/2
  so,
  P(e)=(1/2)*(1/2)*(1/2)
  =1/8

• probability of head or tail for each coin is 1/2
  so total prob. = 1/2*1/2*1/2=1/8
  
  ans 1/8
