Give the sample spaces associated with the following experiments. Say how many simple events there are and list them if there are fewer than ten. If there are more than ten, list three simple events.
1. Two molecules jump in and out of a cell. We record how many molecules are inside at times 1 and 5.
2. Three molecules jump in and out of a cell. We record how many molecules are inside at times 3 and 5.
3. We count how many out of 16 plants are taller than 50 cm.
4. We measure the heights of two plants.
