A density curve for all the possible ages between 0 years and 100 years is in the shape of a triangle. What is the height of the
2 answers:
Answer:
Option D) 0.02 is the answer.
Step-by-step explanation:
Given that a density curve for all the possible ages between 0 years and 100 years is in the shape of a triangle.
We know that probability for any event A = favourable outcomes/total outcomes
Because probability is expressed as a ratio, probability of an event is always positive and lies between 0 and 1.
Hence total probability is always 1.
Under density curve the area represents the total probability and hence total area =1
Area = Area of triangle = 1/2 bh
=
Hence altitude = 0.02
