Answer:
The probability that a person with restless leg syndrome has fibromyalgia is 0.1833.
Step-by-step explanation:
Denote the events as follows:
<em>F</em> = a person with fibromyalgia
<em>R</em> = a person having restless leg syndrome
The information provided is as follows:
P (R | F) = 0.33
P (R | F') = 0.03
P (F) = 0.02
Consider the tree diagram attached below.
Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.1833.
 
        
             
        
        
        
Answer: Angle of elevation of sun at that time is 24.51° .
Step-by-step explanation:
Since we have given that 
Height of a large totem pole near Kalama, Washington = 100 feet
Length of a shadow at noon = 219 foot
 We need to find the angle of elevation of sun at that time .
As  we know the formula for "Tangent ":

Hence, Angle of elevation of sun at that time is 24.51° .
 
        
             
        
        
        
12in=1ft
2.75ft=33in
2.25ft=27in
