Match List I with List II

LIST I LIST II
A. P(X=2) I. $\frac{4}{36}$
B. P(X=4) II. $\frac{5}{36}$
C. P(X=5) III. $\frac{1}{36}$
D. P(X=6) IV. $\frac{3}{36}$

Choose the correct answer from the options given below :

Options:

A-I, B-II, C-III,D-IV

A-II, B-III, C-IV,D-I

A-III, B-IV, C-I, D-II

A-IV, B-II, C-III,D-IV

Correct Answer:

A-III, B-IV, C-I, D-II

Explanation:

The correct answer is Option (3) → A-III, B-IV, C-I, D-II

A. $P(X=2)=\frac{1}{36}$ ((1, 1))

B. $P(X=4)=\frac{3}{36}$ ((1, 3), (3, 1), (2, 2))

C. $P(X=5)=\frac{4}{36}$ ((1, 4), (2, 3), (3, 2), (4, 1))

D. $P(X=6)=\frac{5}{36}$ ((1, 5), (2, 4), (3, 3), (4, 2), (5, 1))
