Answer:
[tex]\frac{7}{12}[/tex]
Step-by-step explanation:
Given that X is to be chosen to be chosen at random from the set {1, 2, 3, 4} and y is at random from the set {5, 6, 7},
Sample space of xy ={5,6,7, 10,12,14, 15,18,21,7,14,21,28}
Subspace containing even numbers = {6,10,12,14,18,14,28}
Probability xy is even = n(even numbers in xy)/n(total numbers in xy)
[tex]\frac{7}{12}[/tex]
