**Probability ncert solutions Chapter 15 Exercise 15.1 Question 19**

**19.** A child has a die whose six faces show the letters A, B, C, D, E and A.

The die is thrown once. What is the probability of getting (i) A? (ii) D?

Solution

**(i)**

Let E be the event of getting A with a single throw of dice.

Number of possible outcomes favorable to event E=2

(There are 2 faces on a dice with A written on them)

Total number of possible outcomes=6 (There are 6 faces on a dice)

P(E)=(Number of outcomes favorable to event E)/(Total number of possible outcomes)

**(ii)**

Let F be the event of getting D with a single throw of dice.

Number of possible outcomes favorable to event F=1

(There is 1 face with letter D on it)

Total number of possible outcomes=6 (There are 6 faces on a dice)

P(F)=(Number of outcomes favorable to event F)/(Total number of possible outcomes)
