Step-by-step explanation:
P (blue)  fraction = 2/8   decimal=.25     percent=25%
P(purple) fraction=0/8   decimal=0         percent =0%
P(not green)  fraction=5/8     decimal=.625     percent= 62.5%
P(not brown) fraction=8/8     decimal=1   percent =100%
2)Refer to the table on air travel selected airports. Suppose a flight that arrived at El Centro is selected at random. What is the probability that the flight did not arrive on time? write your answer as a fraction, decimal and percent.    
80% on time so 20% are not on time
20/100 ÷ 20 =1/5
20%, .2, 1/5
