In a certain game, a ball is randomly selected from a box that contains 3 red balls, 2 green balls and 6 blue balls. If a red ball is selected R5 is won, if green you win R4 and if blue is selected you win nothing. Calculate the probability of winning R4.
First, we need to calculate the total number of balls in the box:
Total balls = 3 (red balls) + 2 (green balls) + 6 (blue balls) = 11 balls
Next, we need to calculate the probability of winning R4, which is selecting a green ball:
Probability of winning R4 = Number of green balls / Total number of balls
Probability of winning R4 = 2 / 11 = 0.1818 or approximately 18.18%
