Question

A child’s game has 8 triangles of which 3 are blue and rest are red and 10 squares of which 6 are blue and rest are red. One piece is lost at random. Find the probability that it is a triangle

Answer 1

Total number of figures

n(S) = 8 triangles + 10 squares = 18

P(lost piece is a triangle) = `8/18 = 4/9`
