Step-by-step explanation:
The number of elements in sample space when a coin is flipped 10 times will be:

Let A be the event that the tails appear 7 times:
Then,

Converting into percentage:

So, option C is correct ..
The function that represent this exponential decay is given as y = A(0.85)ˣ
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value and b is the multiplication factor.
Given that A is the initial value, there is a decay of 15%, hence:
b = 100% - 15% = 0.85
The function that represent this exponential decay is given as y = A(0.85)ˣ
