Answer:
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
Answer:
4/25 or 16%
Step-by-step explanation:
<em>There are </em><em>4</em><em> prime numbers between 1 and 10 (2, 3, 5, 7)</em>
<em>There are </em><em>10</em><em> cards to choose from.</em>
<em>The formula for probability is (success)/(total)</em>
4/10 x 4/10 = 16/100 or 4/25
