Answer:
The experimental probability that the next train to arrive will be on time is P(T) = = 0.875
Step-by-step explanation:
Experimental Probablity is based on the experiments which we have performed in the past. In this case, of the total number of trains (16), the total number of trains which arrived on time is (14). So the probablity tat the next train to arrive will be on time would be calculated as:
=
= 0.875
V=LWH (multiply the length, width and height)
So plug in the numbers, V=6x14x10=840 ft^3 (feet cube)
M is 6 more than 10 so it will be 16
The probability from 1.5 ≤ x ≤ 3 can be calculated by dividing the Area from x=1.5 to x=3 by the total Area of the distribution.
The given distribution is rectangular shaped, so its Area will be = Length x Width = 1 x 3 = 3 square units
From x = 1.5 to x = 3, the length is 1.5 and width is 1. So the area between these two intervals = 1.5 square units.
Thus, <span>P(1.5 ≤ X ≤ 3) = 1.5/3 = 0.5
