Example 2 A bag contains a red ball, a blue ball and a yellow ball, all the balls being of the same size. Kritika takes out a ball from the bag without looking into it. What is the probability that she takes out the yellow ball? Total number of balls = 3 Number of balls which are yellow = 1 P(ball taken out yellow) = (ππ’ππππ ππ πππππ π€βππβ πππ π¦πππππ€)/(πππ‘ππ ππ’ππππ ππ πππππ ) = π/π Example 2 A bag contains a red ball, a blue ball and a yellow ball, all the balls being of the same size. Kritika takes out a ball from the bag without looking into it. What is the probability that she takes out the (ii) red ball? Total number of balls = 3 Number of balls which are red = 1 P(ball taken out red) = (ππ’ππππ ππ πππππ π€βππβ πππ πππ)/(πππ‘ππ ππ’ππππ ππ πππππ ) = π/π Example 2 A bag contains a red ball, a blue ball and a yellow ball, all the balls being of the same size. Kritika takes out a ball from the bag without looking into it. What is the probability that she takes out the (iii) blue ball? Total number of balls = 3 Number of balls which are blue = 1 P(ball taken out blue) = (ππ’ππππ ππ πππππ π€βππβ πππ πππ’π)/(πππ‘ππ ππ’ππππ ππ πππππ ) = π/π
