Step-by-step explanation:
Given that a fair coin is flipped twelve times.
It means the number of possible sequences of heads and tails would be:
2¹² = 4096
We can determine the number of ways that such a sequence could contain exactly 9 tails is the number of ways of choosing 9 out of 12, using the formula
Plug in n = 12 and r = 9
∵
∵
Thus, the probability will be:
Thus, the probability of the coin landing tails up exactly nine times will be:
Answer:
is the answer.
Step-by-step explanation:
Let the equation of the exponential function is,
Two points from the given table which lie on the graph are (0, 0.2) and (1, 0.1)
For a point (0, 0.2),
0.2 =
a = 0.2
For another point (1, 0.1),
0.1 =
b = = 0.5
Therefore, exponential function defined by the given table is,
