Question

1. An unbiased die is thrown. What is the
probability of getting
(a)even number
(b) A multiple of 3
(c) a multiple of 2 or 3
(d) a number less than 5 divisible by 2
(e) a number greater than 2 divisible by 5
(f) An even number or a multiple of 3
(g) an even number and a multiple of 3
(h) a number 3 or 4
(I) an odd number
(j) a number less than 5
K) A number greater than 3
(l) a number between 3 and 6​

Answer 1

Step-by-step explanation:

The traditional die you may be thinking of has six faces, and is numbered 1 2 3 4 5 6, each digit one time. The chances of getting a number that fits one of the three types depends on the type in question. There are 6 faces on the die, and of those, 2, 3, and 5 are prime, resulting in a 3/6 chance of such a roll.

Answer 2

Step-by-step explanation:

Answer

In a single throw of dice, we get 1,2,3,4,5 or 6.

No. of total outcomes =6

(i) Even number or a multiple of 3 are 2,3,4,6

Favourable no. of outcomes = 4

P(even number or multiples of 3)=

4/6

=

2/3

(ii) a number 3 or 4

Favourable no. of outcomes = 2

P(a number 3 or 4)=

2/6

=

1/3

(iii) number greater than 3 are 4,5,6

Favourable no. of outcomes = 3

P(a number greater than 3)=

3/6

=

1/2
