11 is the expected value of the escaped time.
Bv (Bt - Bo0 + (Bt - Bs0
= 4 - 0 + 4+3 = 11
Escape time refers to the time available (and necessary) for a person to escape from a particularly dangerous situation.
Escape time refers to the time available (and required) for a person to escape from a particularly hazardous situation. Understanding escape times is an important part of the hazard assessment process and is a particularly important component of any hazard assessment involving fire, explosion, or potential exposure to toxic substances.
The escape time concept is not simply a function of the time it takes for workers to escape the hazard. It also takes into account and constrains the amount of time workers have to escape before being overwhelmed by the danger. This means that two of her workers trying to escape the same fire may have different escape times if one is wearing a fire suit and the other is not.

Answer: 0.8461
Step-by-step explanation:
Given : 
Let x be the random variable that represents the cost for the hospital emergency room visit.
We assume that cost for the hospital emergency room visit is normally distributed .
z-score for x=1000 ,
Using z-value table , we have
P-value =P(x>1000)=P(z>-1.02)=1-P(z≤ -1.02)=1-0.1538642
=0.8461358≈0.8461 [Rounded nearest 4 decimal places]
Hence, the probability that the cost will be more than $1000 = 0.8461
