There is a bacteria which has the probability of die 1/3 of its total number or it may tripled. Find out the probability
A. P=1/3+(2/3*p^3)
B. P=2/3+(2/3*p^3)
C. P=2/3+(1/3*p^3)
D P=2/3+(2/3*p^3)

• It has to be 1/3 of dieing plus living which is given by 2/3 * p^3 as p is tripled so raised to 3
  probability of die is 1/3
  
  or
  its get tripled
  the probability of tripled is 2/3*p*p*p
  thats 2/3*p^3
  
  so both the probability combined as P=1/3+(2/3*p^3)

• A.P=1/3+(2/3*p^3)
  
  explanation...for die its probability =1/3
  for survive its probability=1-1/3=2/3.
  an given that survive probability is tripled,therefore survive probability=2/3*p^3
  
  so,total probability =1/3+(2/3*p^3)..ans

• probability of die is 1/3
  
  or
  its get tripled
  the probability of tripled is 2/3*p*p*p
  thats 2/3*p^3
  
  so both the probability combined as P=1/3+(2/3*p^3)
  
  Hence option A is correct

  so answer is option A. P=1/3+(2/3)*p^3

• choice
  (a) is the answer for this
  the probability of die is 1/3, so living probability is(1-1/3)=2/3
  so 1/3+(2/3*p^3) is the ans

• Probability of die = 1/3
  or
  it's get tripled.
  The probability tripled is 2/3*p*p*p i.e. 2/3*p^3. So both the probability combined as P=1/3+(2/3*p^3).
