To find the probability that an adult male using the drug will experience nausea, we will use the formula for probability:
\[ P(\text{Nausea}) = \frac{\text{Number of males experiencing nausea}}{\text{Total number of males in the trial}} \]
From the table you provided, we can see:
- Number of males experiencing nausea: 22
- Total number of males in the trial: 1100
Now, we can calculate the probability:
\[ P(\text{Nausea}) = \frac{22}{1100} \]
Calculating this:
\[ P(\text{Nausea}) = 0.02 \]
Therefore, the probability that an adult male using the drug will experience nausea is \(0.02\) or \(2%\).
