It is irrational because it is not a whole number, repeating decimal, or a terminated decimal. It never ends, and it never repeats. Therefore, it cannot be considered an integer.
20 because if you take 20 half it that would be 10 then take away 4 that would then equal 6.
Substitute the values.
2(3)(2)=?
2*3=6
6*2=12
Final answer: 12

I hope this helps :D
Step-by-step explanation:

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
1

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

P
(
¬
X

, where ¬

X
is throwing zero heads.
