Answer:  3/14

======================================================

Explanation:

set of primes given = {2,3,5,7}

everything else is composite

We have 4 primes out of 8 total, so 4/8 = 1/2 is the probability of getting a prime on the first draw.

After we take out a prime, we have 4-1 = 3 left out of 8-1 = 7 total

The probability of getting another prime, after the first one is not replaced, is 3/7

Multiply the fractions to get the final answer

(1/2)*(3/7) = (1*3)/(2*7) = 3/14

Answer:

3/14

Step-by-step explanation:

We have 8 cards: 2,3,4,5,6,7,8,9

prime numbers: 2,3,5,7

P ( prime number) = number of primes/total

                              =4/8= 1/2

We  do not replace the card,  say the 2

We have 7 cards: 3,4,5,6,7,8,9

prime numbers: 3,5,7

P ( prime number) = number of primes/total

                              =3/7

P (prime, no replacement, prime) = 1/2* 3/7 = 3/14
