Answer:
(2.8 x 10^8) / (7 × 10^2) = 400'000
Step-by-step explanation:
Using the binomial distribution, it is found that there is a 0.0108 = 1.08% probability of the coin landing tails up at least nine times.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- The coin is fair, hence p = 0.5.
- The coin is tossed 10 times, hence n = 10.
The probability that is lands tails up at least nine times is given by:

In which:



Hence:

0.0108 = 1.08% probability of the coin landing tails up at least nine times.
