### Access RD Sharma Solutions Class 11 Maths Chapter 33 Exercise 33.2- Important Question with Answers

**1. A coin is tossed. Find the total number of elementary events and also the total number of events associated with the random experiment.**

**Solution:**

Given: A coin is tossed.

When a coin is tossed, there will be two possible outcomes, Head (H) and Tail (T).

Since, the no. of elementary events is 2 {H, T}

We know, if there are n elements in a set, then the number of total element in its subset is 2n.

So, the total number of the experiment is 4,

There are 4 subset of S = {H}, {T}, {H, T} and Փ

∴ There are total 4 events in a given experiment.

**2. List all events associated with the random experiment of tossing of two coins. How many of them are elementary events?**

**Solution:**

Given: Two coins are tossed once.

We know, when two coins are tossed then the no. of possible outcomes are 2^{2} = 4

So, the Sample spaces are {HH, HT, TT, TH}

∴ There are total 4 events associated with the given experiment.

**3. Three coins are tossed once. Describe the following events associated with this random experiment:A = Getting three heads, B = Getting two heads and one tail, C = Getting three tails, D = Getting a head on the first coin.(i) Which pairs of events are mutually exclusive?(ii) Which events are elementary events?(iii) Which events are compound events?**

**Solution:**

Given: There are three coins tossed once.

When three coins are tossed, then the sample spaces are:

S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

So, according to the question,

A = {HHH}

B = {HHT, HTH, THH}

C = {TTT}

D = {HHH, HHT, HTH, HTT}

Now, A⋂ B = Փ,

A ⋂ C = Փ,

A ⋂ D = {HHH}

B⋂ C = Փ,

B ⋂ D = {HHT, HTH}

C ⋂ D = Փ

We know that, if the intersection of two sets are null or empty it means both the sets are Mutually Exclusive.

**(i)** Events A and B, Events A and C, Events B and C and events C and D are mutually exclusive.

**(ii)** Here, We know, if an event has only one sample point of a sample space, then it is called elementary events.

So, A and C are elementary events.

**(iii)** If there is an event that has more than one sample point of a sample space, it is called a compound event.

Since, B ⋂ D = {HHT, HTH}

So, B and D are compound events.
