From the following which number cannot be the probability of any number :

Options

A. `(2)/(3)`
B. `-1.5 `
C. `15 %`
D. `0.7%`

Answer

To determine which number cannot be the probability of any event, we need to recall the basic properties of probabilities. The probability of any event must always lie between 0 and 1, inclusive. This means that:

- The minimum value of probability is 0 (impossible event).
- The maximum value of probability is 1 (certain event).

Now, let's analyze the given options step by step:

### Step-by-Step Solution:

1. **Option 1: \( \frac{2}{3} \)**
- Convert \( \frac{2}{3} \) to a decimal:
\[ \frac{2}{3} = 0.6667 \text{ (approximately)} \]
- Since \( 0.6667 \) is between 0 and 1, this is a valid probability.

2. **Option 2: \( 2 \)**
- The value is \( 2 \).
- Since \( 2 \) is greater than 1, this cannot be a valid probability.

3. **Option 3: \( 15\% \)**
- Convert \( 15\% \) to a decimal:
\[ 15\% = \frac{15}{100} = 0.15 \]
- Since \( 0.15 \) is between 0 and 1, this is a valid probability.

4. **Option 4: \( 0.7\% \)**
- Convert \( 0.7\% \) to a decimal:
\[ 0.7\% = \frac{0.7}{100} = 0.007 \]
- Since \( 0.007 \) is between 0 and 1, this is a valid probability.

### Conclusion:
The only number that cannot be the probability of any event from the given options is **Option 2: \( 2 \)**.
