Answer 1

Here, we have Lactose intolerance = 25% irritable bond syndrome = 10% both = 5% using this information, we will obtain the Venn diagram as since 20 + 5 = 25% lactose and 5 + 5 = 10% Bowell syndrome Now, as the Venn-diagram is overlapping for 5% thus, we can say that they are NOT independent
