The document explains the concepts of simple and compound events in probability for 11th grade students. A simple event consists of one element in the sample space, while a compound event contains more than one element. It also includes examples such as tossing two coins and identifying events based on outcomes.

2. simple and compound events
• Simple Event: If an event E has only one element in a sample space, it is
called a simple event
• Compound Event: If an event E has more than one element in a sample
space, it is called a compound event.

3. simple events
• For an example, let us consider the experiment of tossing two coins. Its
sample space is S = {HH, HT, TH, TT}
• There are four simple events: E1 = {HH}, E2={HT}, E3={TH}, E4={TT}

4. compound events
• Let’s take another event F: “The number turns up is odd or event”
• Therefore F = {1, 2, 3, 4, 5, 6}
• Thus the event F=S is called a sure event
