Answer: A) 0.1
Explanation:
Each of the integers in the first set could be combined with any from the second set, giving a total of 4 x 5 = 20 possible pairs.Of these the combinations that could give a sum of 23 are (5 + 18), and (9 + 14)This means that the probability of getting a sum of 23 is 2/20 = 1/10
