Venn diagrams for statistics

In the intricate field of genetics, understanding the complex relationships between different sets of genes, phenotypes, and their associated probabilities is crucial. This is where the Venn diagram, a simple yet powerful tool, comes into play. Its ability to represent and visualize these relationships has made it indispensable in genetics. Here, the percentages add up to 156%. This is 56% too much. In this total, those who like chocolate and strawberry have been counted twice and so 56% is equal to the number who like both chocolate and strawberry. We can place 56% in the intersection, C∩S We know that the total percentage who like chocolate is 70%, so 70−56=14%−14% like just chocolate. Similarly, 82% like strawberry, so 82−56=26% 82−56=26% like just strawberry.
