66 = (2x - 1) \times (x - 1) \\ 66 = 2 {x}^{2}  - 3 + 1 \\ 65 - 2 {x}^{2}  + 3x = 0 \\  - 65 + 2 {x}^{2}  - 3x = 0 \\ 2 {x}^{2}  + 10x - 13x - 65 = 0 \\ 2x \times (x + 5) - 13 \times (x + 5) = 0 \\ (x + 5) \times (2x - 13) = 0 \\  \\ x + 5 = 0 \\ 2x - 13 = 0 \\  \\ x =  - 5 \\ x =  \frac{13}{2}  \\  \\

Select the statement that does not correctly use probability to describe an event
Nina [5.8K]

Answer:

D

Step-by-step explanation:

Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.

If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.

You can therefore easily understand that it doesn't make sense to have a probability greater than 1, as we have in choice D.
