Answer:
Expected number of hours before the the group exits the building = E[Number of hours] = 3.2 hours
Step-by-step explanation:
Expected value, E(X) is given as
E(X) = Σ xᵢpᵢ
xᵢ = each variable
pᵢ = probability of each variable
Let X represent the number of hours before exiting the building taking each door. Note that D = Door
D | X | P(X)
1 | 3.0 | 0.2
2 | 3.5 | 0.1
3 | 5.0 | 0.2
4 | 2.5 | 0.5
E(X) = (3×0.2) + (3.5×0.1) + (5×0.2) + (2.5×0.5) = 3.2 hours

Using proportions, it is found that his DAILY RATE on that particular day is of Php 2,420
.
- This question is solved by proportions, using a <em>rule of three.</em>
- In a regular 8-hour day, Allen earns Php 1420. How much will he earn on a 14 hour day?
The <em>rule of three</em> is:
8 hours - Php 1420
14 hours - x
Applying cross multiplication:
![8x = 1420 \times 14](https://tex.z-dn.net/?f=8x%20%3D%201420%20%5Ctimes%2014)
![x = \frac{1420 \times 14}{8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1420%20%5Ctimes%2014%7D%7B8%7D)
![x = 2485](https://tex.z-dn.net/?f=x%20%3D%202485)
The closest option is Php 2,420.
