Given below is the distribution of a random variable X If = P (X 3) and = P (X 2) , then : =

Options

  1. A2: 5
  2. B3: 4
  3. C4: 5
  4. D3: 7

Correct answer

D. 3: 7

Step-by-step solution

For a distribution of random variable x , =P (X^6 3 )=P (X^6=1 )+P (X^6=2 ) aligned & = +2 =3 & and =P (X^6 2 )=P (X^6=3 )+P (X^6=4 ) & =3 +4 =3 & : =3: 7 aligned
