A bag contains three balls: one red, one blue, and one yellow. All the balls are of the same size. Kritika randomly selects a ball from the bag without looking. Determine the probability that she selects:
(i) The yellow ball
(ii) The red ball
(iii) The blue ball
Solution:
In this case,
The total number of possible outcomes is 3 (since there are 3 balls).
(i) The number of favourable outcomes for selecting the yellow ball is 1.
Thus, the probability of selecting the yellow ball is:
P(Y) = 1/3
(ii) The number of favourable outcomes for selecting the red ball is 1.
Thus, the probability of selecting the red ball is:
P(R) = 1/3
(iii) The number of favourable outcomes for selecting the blue ball is 1.
Thus, the probability of selecting the blue ball is:
P(B) = 1/3
Therefore, the probability of selecting any one of the three balls (yellow, red, or blue) is 1/3
