In Exercises 10 to 12, the probability is the ratio n u m b e r   o f   f a v o r a b l e   o u t c o m e s n u m b e r   o f p o s s i b l e     o u t c o m e s . Use Example 2 of this section as a guide.Assume that a die in the shape of a regular icosahedron is rolled. What is the likelihood thata) 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=mn=Number of favorable outcomesTotal number of outcomes

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.
