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.
To calculate the probability of winning R4, we first need to determine the total number of possible outcomes when selecting a ball from the box.
There are a total of 3 red balls, 2 green balls, and 6 blue balls, giving a total of 3 + 2 + 6 = 11 possible outcomes.
The probability of winning R4 (selecting a green ball) is the number of favorable outcomes (2 green balls) divided by the total number of possible outcomes.
Therefore, P(winning R4) = 2/11 ≈ 0.1818
So, the probability of winning R4 is approximately 0.1818 or 18.18%.
