To determine the experimental probability of landing on a number greater than or equal to 4, we first need to identify the outcomes that satisfy this condition. The numbers greater than or equal to 4 are 4, 5, and 6.
Now, we can find the total frequency of these outcomes from the table:
- Frequency of 4: 6
- Frequency of 5: 9
- Frequency of 6: 7
Now, we add these frequencies together: \[ 6 + 9 + 7 = 22 \]
Next, we calculate the total number of tosses, which is given as 50.
The experimental probability \( P(\geq 4) \) can be calculated as follows: \[ P(\geq 4) = \frac{\text{Total frequency of outcomes 4, 5, and 6}}{\text{Total number of tosses}} = \frac{22}{50} \]
Simplifying this fraction: \[ P(\geq 4) = \frac{22}{50} = 0.44 \]
Therefore, the experimental probability of landing on a number greater than or equal to 4 is: \[ \boxed{0.44} \]
