Based on the data provided, the estimated probability that there will be an empty space in car park "A" the next time Lily drives to the college is 80%.
Calculation: 12 times out of 15 times, the car park was not full, so the probability of finding an empty space is 12/15 = 0.8, or 80%.
In the last 15 times that Lily had driven to the college, she was able to find a space in car park "A" 12 times. Estimate the probability that there will be an empty space in car park "A" the next time she drives to the college.
