**Below are the MCQs for chapter 15-Probability.**

**1. The probability of event equal to zero is called;**

(a)Unsure event

(b)Sure Event

(c)Impossible event

(d)Independent event

Answer: c

Explanation: The probability of an event that cannot be happened or which is impossible is equal to zero.

**2. The probability that cannot exist among the following:**

(a)⅔

(b)-1.5

(c)15%

(d)0.7

Answer: b

Explanation: The probability lies between 0 and 1. Hence it cannot be negative.

**3. If P(E) = 0.07, then what is the probability of ‘not E’?**

(a)0.93

(b)0.95

(c)0.89

(d)0.90

Answer: a

Explanation: P(E) + P(not E) = 1

Since P(E) = 0.05

So, P(not E) = 1 – P(E)

Or, P(not E) = 1 – 0.07

∴ P(not E) = 0.93

**4. A bag has 3 red balls and 5 green balls. If we take a ball from the bag, then what is the probability of getting red balls only?**

(a)3

(b)8

(c)⅜

(d)8/3

Answer: c

Explanation: Number of red balls = 3

Number of green balls = 5

Total balls in bag = 3+5 = 8

Probability of getting red balls = number of red balls/total number of balls

= ⅜

**5. A bag has 5 white marbles, 8 red marbles and 4 purple marbles. If we take a marble randomly, then what is the probability of not getting purple marble?**

(a)0.5

(b)0.66

(c)0.08

(d)0.77

Answer: d

Explanation: Total number of purple marbles = 4

Total number of marbles in bag=5+8+4=17

Probability of getting purple marbles = 4/17

Hence, the probability of not getting purple marbles = 1-4/17 = 0.77

**6. A dice is thrown in the air. The probability of getting odd numbers is**

(a)½

(b)3/2

(c)3

(d)4

Answer: a

Explanation: A dice has six faces having values 1, 2, 3, 4, 5 and 6.

There are three odd numbers and three even numbers.

Therefore, the probability of getting only odd numbers is = 3/6 = ½

**7. If we throw two coins in the air, then the probability of getting both tails will be:**

(a)½

(b)¼

(c)2

(d)4

Answer: b

Explanation: When two coins are tossed, the total outcomes will be = 2 x 2 = 4

Hence, the probability of getting both tails = ¼

**8. If two dice are thrown in the air, the probability of getting sum as 3 will be**

(a)2/18

(b)3/18

(c)1/18

(d)1/36

Answer: c

Explanation: When two dice are thrown in the air:

Total number of outcome = 6 x 6 = 36

Sum 3 is possible if we get (1,2) or (2,1) in the dices.

Hence, the probability will be = 2/36 = 1/18

**9. A card is drawn from the set of 52 cards. Find the probability of getting a queen card.**

(a)1/26

(b)1/13

(c)4/53

(d)4/13

Answer: b

Explanation: Total number of cards = 52

Number of queen cards= 4

The probability of getting queen card = 4/52 = 1/13

**10. A fish tank has 5 male fish and 8 female fish. The probability of fish taken out is a male fish:**

(a)5/8

(b)5/13

(c)13/5

(d)5

Answer: b

Explanation: Total fish = 5+8 = 13

Probability of taking out a male fish = 5/13
