Which of the following is not a probability of Mary scoring 85% in a mathematics test?
0.15
0.57
0.94
1.01
설명
The probability not scoring 85% is = 1 - pro(scoring 85%)
= 1 - \(\frac{85}{100}\) = 1 - 0.85
= 0.15
not scoring would be less than 1. Hence option D is correct because the probability of an event cannot be more than 1.
