Which of the following values cannot be probabilities 27 72
Which of the following values cannot be probabilities? 2/7 , 7/2, -0.2 , 2%, 2, 120%. 0. 0/119
Solution
We have to given the values, and we have to verify that these values are probability or not.
The condition for the probability is the given value is greator than 0 and not exceed 1.
That is 0 value 1
a) 2 / 7 = 0.2857
2/7 is lies between 0 and 1 so this value is probability.
b) 7/2 = 3.5
7/2 is greator than 1 so this value is not a probability.
c) - 0.2
-0.2 is not probability because probability can\'t be negative.
d) 2% = 2/100 =0.02
2% is probability because it lies between 0 and 1.
e) 2
2 is not probability because probability does not exceed 1.
f) 120% = 120/100 = 1.2
120% is not probability because this value is greator than 1.
g) 0
0 is the probability because probability lies between 0 and 1.
h) 0/119 = 0
0/119 is the probability because probability lies between 0 and 1.
So the 7/2, -0.2,2,120% are not probabilities.
