The correct answer is 17/20 or 85%. This can be calculated by taking the number of units that passed inspection (1000 - 150 = 850) and dividing by the total number of units inspected (1000). So, 850/1000 = 17/20 = 85%.

A coin is flipped six times and the head appears four times.
A coin is flipped six times and the head appears four times.
A coin is flipped six times and the head appears five times.
A coin is flipped six times and the head appears five times.
A coin is flipped six times and the head appears three times.
A coin is flipped six times and the head appears three times.
A coin is flipped six times and the head appears each time.
The scenario in which the experimental probability is equal to the theoretical probability is:
A coin is flipped six times and the head appears three times.
In this scenario, the theoretical probability of getting a head on each flip is 0.5, and the experimental probability based on the result of flipping the coin six times is also 0.5 for getting a head on each flip.
