Question

A real life problem of late coming of a train can be solved by
A) Trigonometry
B) Probability
C) Geometry
D) None

Answer 1

Hint:
Here, we will use the fact that trigonometry is used to solve the problems related to the shapes of the triangle. Geometric problems involve dimensional shapes and the probability problem involve the certainty of an event.

Complete step by step solution:
We have given that the train is coming late.
Here, we know that trigonometry is the branch of mathematics which deals with the relations of the angles and sides of the triangle and the functions of the angles, but the late coming of the train does not involve any relation with the sides and angles of the triangle. Thus, the problem of the late coming of the train cannot be solved by trigonometry.
Also, we know that geometry is the branch of mathematics which deals with the dimensions of the lines, surfaces and the shapes. But the late coming of the train does not involve any relation with the dimensions of the lines, surfaces and the shapes. Thus, the problem of the late coming of the train cannot be solved by Geometry.
We know that probability is the chance of happening of the events, the problem of late coming of the train relates with the certainty and uncertainty of the events. Thus, the problem would be solved by the probability.

Hence, the correct option is C.

Note:
To solve the above question one has to have knowledge of trigonometry, geometry and Probability. In trigonometry we have only problems related to the triangles and their angles. In geometry we have a problem related to the dimensions of the shapes and the surfaces and in the probability, we have the problems related to the chance of the happening of the event. Because we have to take the examples and compare them with each option to find the correct one.
