Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

**Exercise: Events with Two Dice**
Suppose two dice (one red, one green) are rolled. Consider the following events:
- **A:** The red die shows 5.
- **B:** The numbers add to 6.
- **C:** At least one of the numbers is 1.
- **D:** The numbers do not add to 9.
**Task:** Express the given event in symbolic form.
**Given Statement:**
Either the numbers add to 6, or they add to 9, or at least one of them is 1.
**Symbolic Options:**
- ( ) \( B \cap D' \cup C \)
- ( ) \( B' \cup D' \cup C \)
- ( ) \( B \cup D' \cup C \)
- ( ) \( B \cup D' \cup C' \)
- ( ) \( B \cup D' \cap C \)
**Question:**
How many elements does it contain?
[Answer Box: _______]

The sample S here is the set of all ordered pair (R, G)
Where R=Red die and G=green die.
Therefore, n(S)=36
Given are the following events-
A: - The red die shows 5
B: - The numbers add to 6
C: - At least one of the numbers is 1
D: - The number do not add to 9
