Heads Or Tails?

APPH12-KBL3KV

Students make predictions about probability and test it with flipping coins. Each of four students in a lab group flips a coin and records whether the coin lands with a head or a tail. Data is recorded in a chart. They repeat this multiple times and compare the results to their predictions.

Which student predictions are consistent with a large number of trials?

Choose TWO answers.

A

Student one predicts that two heads and two tails will be the most probable arrangement in the throws.

B

Student two predicts that the total number of heads and tails in all the arrangements have the the same probability since there is a 50% chance of either heads or tails occurring.

C

Student three predicts that there is a better chance of having either three heads or three tails.

D

Student four states that you would need more coins to make a valid prediction since probability theory depends on very large numbers.
