Answer:

The circumference of a circle = 2πr = 9π inches

Or, 2πr = 9π

Or, r = 9/2

Or, r = 4.5 inches

The area of a circle = πr²

Or, The area of a circle = π×4.5×4.5

Or, The area of a circle = 20.25π square inches

We can solve this problem using the binomial distribution. A binomial distribution<span> can be thought of as a success or failure outcome in an experiment or survey that is repeated multiple times. 
</span>Probability function of binomial distribution has the following form:
P= \frac{n!}{k!(n-k)!} p^k(1-p)^{n-k}
p represents the probability of each choice we want. k is the number of choices we want and n is the total number of choices.
In our case p=0.85, k=5 and n=6. 
We can now calculate the answer:
P= \frac{6!}{5!(6-5)!} 0.85^5(1-0.85)^{6-5}=0.39
The probability is 39%.
