10 cards are numbered from 1 through 10. The cards are drawn at random. If two cards are drawn with replacement, find the probability of choosing a prime number in both the first and the second draw.

P(prime,prime) = 4/10 x 4/10 or 2/5 x 2/5 = 4/25

Step-by-step explanation:

2,3,5,7 are primes from 1 through 10

probability of drawing a prime card is 4/10

4/25  or  16%

Step-by-step explanation:

There are 4 prime numbers between 1 and 10 (2, 3, 5, 7)

There are 10 cards to choose from.

The formula for probability is (success)/(total)

4/10  x  4/10  =  16/100 or 4/25

2 is the final ! : )

40% off the regular price is the correct answer.
