There is a biased dice..wen d dice is thrown. probability of occurrence of odd numbers is thrice that of even numbers. If the dice is thrown twice..find the probability of the products of the numbers appeared being odd.

• since, p(odd)=3p(even)
  and p(odd)+p(even)=1
  hence p(odd)=3/4
  now only odd*odd=odd
  hence two odd i s p(odd)=3/4*3/4=9/16

• suppose probability of even num is x
  so probabilty of odd num is 3x
  total probability is = 1
  x+3x=1
  x=1/4(even)
  3x=3/4(odd)
  now product of two odd number gives only odd number
  so probabilty=3/4 x 3/4 = 9/16
  so
