Instructions
Consider the following information and answer questions based on it.
Among 60 students. 12 like only algebra, 13 like only geometry, 10 like only trigonometry, 5 like both algebra and trigonometry, 8 like only physics, 5 like both physics and geometry and the remaining like both algebra and physics.
Solution
Algebra and Phy = (total - algebra-phy-geometry- tri-phy and geo - algebra and tri)
= (60-12-8-13-10-5-5)
= 7
=phy and geo + algebra and tri + algebra and phy
= 5+ 5+7 = 17
