Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data A recent article in a college newspaper stated that college students get an average of 5.5 hrs. of sleep each night
Discuss about total college students so

Answer:
7:9
Step-by-step explanation:
Number of red balls = 10
Number of green balls = 6
Number of orange balls = 15
Number of blue balls = 14
Total numbers of balls = 45
Probability (odds against the red ball) = P( not red)
P(not red) = P(green) + P (orange) + P (blue)------------------------- (1)
P (green) = 6/45
P ( orange) =15/45
P (blue) = 14/45
Substituting in (1)
P(not red) = 6/45 + 15/45+14/45
= 35/45
= 7/9
