If `n` integers taken at random are multiplied together , then the probability that the last digit of the product is 1, 3, 7, or 9 is a. `2^n//5^n` b. `4^n-2^n//5^n` c. `4^n//5^n` d. none of these

If n positive integers are taken at random and multiplied together, then the probability that the last digit of the product is 2,4,6 or 8 is

If n positive integers are taken at random and multiplied together, then the probability that the last digit of the product is 2,4,6 or 8, is

If n positive integers are taken at random and multiplied together, then the probability that the last digit of the product is 2,4,6 or 8, is

If n positive integers taken at random are multiplied together.

If n positive integers taken at random are multiplied together.

n whole numbers are randomly chosen and multiplied. Now, match the following lists. {:(" List I"," List II"),("a. The probability that the last digit is 1, 3, 7, or 9 is","p.
