Question: what is the probability of a randomly selected positive integer raised to an arbitrary positive integer ending in the number 1?
The answer is 0.04 I am unsure how this can be arrived at.
My understanding is that any integer ending in 1 will always end in 1 when raised to any positive integer.
No even number will ever end in 1 when raised to any positive integer.
Numbers ending in 9 will end in a 1 when raised to any multiple of 2
Numbers 3 and 7 will end in 1 when raised to any multiple of 4.
Numbers ending in 5 will never end in a 1.
