50​%.
​(Type an integer or a​ decimal.)
Part 2
Based on​ Liz's results, the experimental probability of the coin landing heads up is
  
70​%.

Part 3
The theoretical probability is
▼
greater
less
than the experimental probability in this experiment.

Answer 1

Part 1: The theoretical probability of the coin landing heads up is **50%**.

Part 2: Based on Liz's results, the experimental probability of the coin landing heads up is calculated as follows:

Experimental Probability = (Number of Heads) / (Total Flips) = 49 / 70 = 0.7, or **70%**.

Part 3: The theoretical probability is **less** than the experimental probability in this experiment.

So the completed statements are:

Part 1: 50%
Part 2: 70%
Part 3: less
