It is 10% lower than the theoretical probability.

It is equal to the theoretical probability for this data.

The experimental probability cannot be concluded from the data in the table.

Answers

It is 10% higher than the theoretical probability.

Heads   Tails

90         60

probability of getting heads:

60%

60% - 50% = 10% higher than theoretical probability.

probability of getting tails:

(60/150)*100

40%

probability of getting heads is 10% more than tails.Not equal.
