Given

You flip 3 coins 20 times and record the number of heads.

Number of heads: 0  1  2 3

Frequency : 2 7 9 2

Toss experiment;

Tossing a coin many different times does not change the probability of getting a head (or tail) for the next toss.

The true statements about the result of the coin toss experiment described are :

• You would expect to get 0 heads and 3 heads about the same number of times.

• You would expect to get 1 head and 2 heads about the same number of times Expected Number of 0 heads = 2.

The experiment cannot be used to model the events in the options as it only gives the number of occurrences of a single event.

Expected Number of 3 heads = 2

Expected Number of 1 head = 7

Expected Number of 3 heads = 9

Therefore, the expected number of 3 and 0 heads are the same. And the expected number of 1 and 2 heads are almost the same.
