Statistics..a box has 1 red marble and five green marble. four draws are made at random.?

Question

find the chance that a red ball appears atleast twice...please explain it to me....thank you

Answer 1

the marbles may not be taken out after they are drawn

so the red marble could be chosen 4 times

Answer 2

none theres only 1 red marble not two

Answer 3

put the red marble back in the box each time you draw it out is one way

Answer 4

there are 6 marbles in all= 1 red + 5 green

therefore your chances are 1 in 6 that a red marble is chosen each time. and yes it could be drawn every time but you asked for the chance percentage right? which is like 16% chance.

Answer 5

Aiya... open your eyes and draw... lol..
