*In Exercises 10 to 12, the probability is the ratio
*

Assume that a die in the shape of a regular icosahedron is rolled. What is the likelihood that

a) an odd number results?

b) a prime number (2, 3, 5, 7, 11, 13, 17 or 19) results ?

c) the result is larger than 2?

To determine

a)

**To find:**

The probability of an odd number result on rolling a die.

Explanation

**Approach:**

If there are *n* elementary events associated to a random experiment such that *m* of them are favorable to an event *A* then,

Probability of happening of *A*=

Consider a die in the shape of a regular icosahedron. The die will have all twenty faces as congruent equilateral triangles. The faces will be numbered from 1 to 20. Assuming each face has an equal chance of being rolled

To determine

b)

**To find:**

The probability of a prime number result on rolling a die.

To determine

c)

**To find:**

Probability of a result larger than 2 on rolling a die.
