Answer:
19/72
Step-by-step explanation:
To calculate the probability that a randomly-chosen child from this group likes either Chess or Swimming but not Football?
We already know the number that liked chess only which is 10, we have to solve for those that liked swimming only which is

x which represent swimming only is
40-31 = 9
Thus probability = 10/72 + 9/72 = 19/72
