There is a box with two colored balls, red balls and blue balls. The probability of selecting a red ball is 10%. The balls are independent of each other, and after each trial of choosing a ball, you put it back in the box.

1.) What is the probability your first red ball that you get will be on your 3rd or 5th trial?

2.) What is the probability your first red ball will be on an even trial? (Trial 2,4,6, etc.)
