Using it's concept, it is found that there is a 0.45 = 45% experimental probability of the coin landing on tails.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, 9 out of 20 trials resulted in tails, hence the experimental probability is given by:
p = 9/20 = 0.45 = 45%.
