To calculate the probability that all three dog biscuits are bacon-flavored based on Desmond's simulation, we need to look at the number of trials where both coins landed on heads three times, since each pair of heads represents a bacon-flavored biscuit.
According to the table in the image, this happened 4 times out of 200 trials. To find the probability, we divide the number of successful trials by the total number of trials:
\[ \text{Probability} = \frac{\text{Number of successful trials}}{\text{Total number of trials}} = \frac{4}{200} \]
Let's do the calculation to find the percentage.
Based on Desmond's results, the probability that all three dog biscuits are bacon-flavored is 2%.
