he events are not independent
<h3>How to determine if they are mutually exclusive?</h3>
The given parameters are:
P(A) = 0.2
P(B) = 0.2
The events are mutually exclusive.
So, as have
P(A or B) = P(A) + P(B)
If the events are independent, then
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = P(A) * P(B)
So, we have
P(A and B) = 0.2 + 0.2 - 0.2 - 0.2 = 0
P(A and B) = 0.2 * 0.2 = 0.04
The above equations are not equal
Hence, the events are not independent

Answer:
Thus, the ratio is:
a:b = 1:4
Step-by-step explanation:
Given the expression
Divide both sides by 2
Divide both sides by b
Thus, the ratio is:
a:b = 1:4
Speed=distance/time
Diana: (3/8)/5=3/(5*8)=3/40 mi/s=0.075 mi/s
Fernando: 2 1/2 miles=5/2 miles
(5/2)/(3/4)
multiply outer values and divide by the inner values:
=(5*4)/(2*3)=20/6=10/3 mi/h= 3 1/3 mi/h=3.3...mi/h
