A bag contains 3 red and 2 blue marbles. A marble is drawn at random. The probability of drawing a black marble is :

1. 0

2. $\dfrac{1}{5}$

3. $\dfrac{2}{5}$

4. $\dfrac{3}{5}$

Assertion (A): The probability that a leap year has 53 Sundays is $\dfrac{2}{7}$.

Reason (R): The probability that a non-leap year has 53 Sundays is $\dfrac{5}{7}$.

1. Assertion (A) is true, but Reason (R) is false.

2. Assertion (A) is false, but Reason (R) is true.

3. Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct reason for Assertion (A).

4. Both Assertion (A) and Reason (R) are correct, and Reason (R) is incorrect reason for Assertion (A).

Assertion (A): If the probability of occurrence of an event E is $\dfrac{5}{11}$, then the probability of non-occurrence of the event E is $\dfrac{7}{11}$.

Reason (R): If E is an event, then P(E) + P($\overline{E}$) = 1.

1. Assertion (A) is true, but Reason (R) is false.

2. Assertion (A) is false, but Reason (R) is true.

3. Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct reason for Assertion (A).

4. Both Assertion (A) and Reason (R) are correct, and Reason (R) is incorrect reason for Assertion (A).

Assertion (A): In a throw of two fair points once, the probability of getting one head is $\dfrac{1}{2}$.

Reason (R): In a throw of two fair coin, the sample space is HH, HT, TH, TT.

1. Assertion (A) is true, but Reason (R) is false.

2. Assertion (A) is false, but Reason (R) is true.

3. Both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct reason for Assertion (A).

4. Both Assertion (A) and Reason (R) are correct, and Reason (R) is incorrect reason for Assertion (A).
