Four people, in turn, are going to choose a marble randomly from a jar containing nine marbles, labeled 1 2 3 4 5 6 7 8 9. Each person will replace his/hers marble after choosing. In how many ways can these four people choose?

Sorry this is a write in not a multiple choice!

36 ways

Step-by-step explanation:

This is probability with replacement

Each of them want to choose a marble randomly from a jar containing nine marbles

The number of ways these four people can choose will be

4( 9 combination 1) that is

4( 9C1) = 4[9!/(9-1)! 1!]

= 4[9!/8!]

= 4(9)

= 36 ways

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
