Question

A Glass Jar contains 1 Red, 3 Green, 2 Blue and 4 Yellow marbles. If a single marble is chosen then Match List I with List II :

List I	List II
A. Probability of yellow marble	I. $\frac{3}{10}$
B. Probability of green marble	II. $\frac{7}{10}$
C. Probability of either green or yellow marble	III. $\frac{1}{2}$
D. Probability of either red or yellow marble	IV. $\frac{4}{10}$

Choose the correct answer from the options given below:

Accepted Answer

C. Total marbles $= 1 + 3 + 2 + 4 = 10$. - A: $P(	ext{Yellow}) = \frac{4}{10} \implies 	ext{IV}$ - B: $P(	ext{Green}) = \frac{3}{10} \implies 	ext{I}$ - C: $P(	ext{Green or Yellow}) = \frac{3+4}{10} = \frac{7}{10} \implies 	ext{II}$ - D: $P(	ext{Red or Yellow}) = \frac{1+4}{10} = \frac{5}{10} = \frac{1}{2} \implies 	ext{III}$ Matches: (A)-(IV), (B)-(I), (C)-(II), (D)-(III).
