Throw a cube numbered from 1 to 6. What is the probability of the number 7, or a number greater than 4, appearing?

1. Identify the total possible outcomes when rolling a six-sided cube:

6

2. Determine the number of favorable outcomes. The cube does not have a number 7, but it does have 5 and 6 which are greater than 4:

2

3. Calculate the probability using the formula

P(A) = \frac{\text{number of favorable outcomes}}{\text{total number of possible outcomes}}

4. Substitute the values:

P = \frac{2}{6} = \frac{1}{3}

Therefore, the probability is \frac{1}{3}.
