Question

a die is thrown once . find the probability 1 a composite no 2 a prime no

Answer 1

Answer:

s={1,2,3,4,5,6}

p(s)=6

n(e)=p(a)/P(s)

1.a composite no:

   a={4,6}

    p(a)=2

n(e)=2/6=1/3

2. a prime number:

  a={2,3,5}

p(a)=3

n(e)=3/6=1/2

Answer 2

2,3,5 prime number

4,6 composite number

probality of composite number is=

2/6

probability of prime number is= 3/6
