It can be done a lot easier: instead of calculating the probability of one head, two heads, three heads, ... one just needs to calculate the probability of no heads: that is simply 0.5
0.5
n
. If you subtract it from 1, you get the probability you want: it's because that's the chance of not no heads, meaning at least one head. So, the formula is: 1−0.5

0.5
n
More formally: if X is throwing at least one head,
()=1−(¬)
P
(
X
)
=
1
−
P
(
¬
X
)
, where ¬
¬
X
is throwing zero heads.

Answer: 3.5</h3>
=========================================
Explanation:
Start by sorting the values from smallest to largest. This is known as ascending order. The original set {3, 5, 7, 4, 3, 1} will sort to {1, 3, 3, 4, 5, 7}
After the values are sorted, we will look at the middle most value to find the median. Because there are six items in this data set, the median number is between slot 3 and slot 4. Note how the sorted data set breaks down into
{1, 3, 3} and {4, 5, 7}
we see that 3 and 4 are tied for the middle most, so the median must be 3.5 which is halfway between 3 and 4.
Example:
4 ÷ 2 = 2 but 2 ÷ 4 = 0.5
In general a ÷ b ≠ b ÷ a, then division is not commutative
㏒₆₄(0.5) = x
64ˣ = 0.5
㏑(64ˣ) = ㏑(0.5)
x㏑(64) = ㏑(0.5)
x㏑(2⁶) = ㏑(2⁻¹)
6x㏑(2) = -㏑(2)
6㏑(2) 6㏑(2)
x = ⁻¹/₆
