In this video, I go over an Venn Diagram word problem using an IB Applications & Interpretation question from May 2024 Paper 1 Question 2.

Stay tuned as I continue to work through the solutions for this and other IB exams.

Excerpt from the question:
A teacher surveys their students to find out if they have eaten at the local Thai and Indian cafés. The results of the survey are shown in the following Venn diagram.

(a) Write down the number of students surveyed. [1]
(b) Write down the number of students who have not eaten at the Indian café. [1]
A student is chosen at random from those surveyed.
(c) Find the probability this student has eaten at both the Thai café and the Indian café. [1]
Let T be the event: a student has eaten at the Thai café.
Let I be the event: a student has eaten at the Indian café.
(d) Find P(T U I ). [1]
(e) State whether the events T and I are mutually exclusive. Justify your answer.
