We have that
the total <span>sold tickets is -------------------------- >600
</span>
the probability of winning with 1 ticket
<span>P=1/600=0.001667---------------- > 0.17%
</span>the probability of winning with 8 ticket
P=(1/600)*8=0.0133---------------- > 1.33%
<span>
the answer is </span>1.33%<span>

121.3 grams of caffeine is remaining in her blood
<h3>How to determine the amount of caffeine?</h3>
The given parameters are:
- Initial, a = 175 mg
- Rate, r = 11.5%
- Time, t = 3 hours
The amount of caffeine is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 175 * (1 - 11.5%)^t
At 3 hours, we have:
A(3) = 175 * (1 - 11.5%)^3
Evaluate
A(3) = 121.3
Hence, 121.3 grams of caffeine is remaining in her blood
