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%
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.
