If the probability of an event is p, then which of the following holds true?

1. −1 ≤ p ≤ 1

2. 0 ≤ p ≤ ∞

3. 0 ≤ p ≤ 1

4. −∞ < p < ∞

In a single throw of a die, the probability of getting a number greater than 4 is:

1. $\Big(\dfrac{1}{2}\Big)$

2. $\Big(\dfrac{1}{3}\Big)$

3. $\Big(\dfrac{1}{4}\Big)$

4. $\Big(\dfrac{2}{3}\Big)$

A die is thrown once. The probability of getting a number which has at least two factors is:

1. 1

2. $\Big(\dfrac{1}{2}\Big)$

3. $\Big(\dfrac{2}{3}\Big)$

4. $\Big(\dfrac{5}{6}\Big)$

There are 3 yellow, 5 white and 7 green balls in a bag. A ball is drawn from the bag at random. The probability that the ball drawn is not white, is:

1. $\Big(\dfrac{1}{3}\Big)$

2. $\Big(\dfrac{2}{3}\Big)$

3. $\Big(\dfrac{3}{5}\Big)$

4. $\Big(\dfrac{1}{2}\Big)$
