different possibilities
(b)
![P(even die 1): \frac{1}{2}](https://tex.z-dn.net/?f=P%28even%20die%201%29%3A%20%5Cfrac%7B1%7D%7B2%7D)
![P(even die 2): \frac{1}{2}](https://tex.z-dn.net/?f=P%28even%20die%202%29%3A%20%5Cfrac%7B1%7D%7B2%7D)

Answer:
(14a+3, 21+4) = 1
Step-by-step explanation:
We are going to use the Euclidean Algorithm to prove that these two integers have a gcd of 1.
gcd (14a + 3, 21a + 4) = gcd (14a+3, 7a + 1) = gcd (1, 7a+1) = 1
Therefore,
(14a + 3, 21a + 4) = 1
