Question

a dice is thrown . find the probability of getting: 1 prime No 2 Odd no 3 No smaller than 4​

Answer 1

Answer:

0.5 in all of three cases

Step-by-step explanation:

When a die is thrown once the sample space will be n(S)=6.

1. Now, let A be the case of getting a prime no.

There are three prime no. on a die ie. 2,3,5.

So Probability of getting a prime no. is

P(A) = 3/6

= 0.5

2. Probability of getting an odd number: 50%

Odd no. on a dice (1, 3, or 5)

so P(B) = 3/6

= 0.5

3. probability of getting no. smaller than four

there are three smaller no. ( 1,2, or 3)

P(C) = 3/6

= 0.5
