Explanation / Answer
H - Hot chocolate
T - Tea
C - Coffee
Given that HTC = 1, TC = 17, HC=4, HT = 3, H =12, T = 42, C=28
The venn diag is given below
a) Atleast = 59
b) exactly one of the three hot beverages mentioned = 6+23+8 = 37
c) at most two of the three beverages = Total - no drinks - all 3
= 72-13- 1 = 58
