Answer:
0.06 = 6% probability of landing open side up.
0.14 = 14% probability of landing closed side up.
0.8 = 80% probability of landing on its side.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. For an experimental probability, these numbers are taken from previous trials.
Landing open side up:
3 out of 50, so:

0.06 = 6% probability of landing open side up.
Landing closed side up:
7 out of 50, so:

0.14 = 14% probability of landing closed side up.
Landing on its side:
40 out of 50, so:

0.8 = 80% probability of landing on its side.
