12:04 PM =
49.From randomly chosen a number from
1 to 8.find the probability that it is a
prime number:
O (A) 1/3
O (B) 1/2
O (C) 1/8
O (D) 3/8​

Answer 1

Answer:

B

Step-by-step explanation:

A={2,3,5,7}

S={1,2,3,4,5,6,7,8}

.

n(A)=4

n(S)=8

.

p(A)=n(A)/n(S)

=4/8

=1/2

hence,p(A)=1/2

Answer 2

Answer:

B 1/2

Step-by-step explanation:

total number n(s)=12345678

prime number b/w 1 to 8 are =2,3,5,7

n(e)=4

probability = n(e)/n(s)

=4/8

=1/2
