here is ur answer ***

Example =1...
Two cards are being chosen from a deck of 5252 cards. Find the probability that both are Jack.
Solution:
The probability of first card being jack = 452452
Now, there are 5151 cards where 33 kings are present.
The probability of second card being jack = 351351
The probability that both of them are jack = 452452 ×× 351351= 12211221
-----------------------------------------------------------------------------
Example 2:
A dice has six sides out of which two sides have 66written on them, and other four sides have 1, 2, 3, 41, 2, 3, 4written on them. Which all are equally likely outcomes when the dice is rolled?
Solution:
The set of outcomes = {1, 2, 3, 4, 6}{1, 2, 3, 4, 6}
Probability of getting a 11 = 1616
Probability of getting a 22 = 1616
Probability of getting a 33 = 1616
Probability of getting a 44 = 1616
Probability of getting a 66 = 2626 = 1313
The outcomes with same probability are 1, 2, 3, 41, 2, 3, 4.
Hence, {1, 2, 3, 4}{1, 2, 3, 4} are equally likely outcomes.
-------------------------------------------------------------------------------
Example 3:
There is bag having 22 red, 33 green and 33 yellow balls. Out of the given events which are equally likely?
a) Getting a green ball and getting a yellow ball.
b) Getting a red ball and getting a yellow ball.
Solution:
a) The probability of getting a green ball = 3838
The probability of getting a yellow ball = 3838
As the probabilities of both the events are same, they are equally likely.
b) The probability of getting a red ball = 2828
The probability of getting a yellow ball = 3838
As the probabilities of both the events are not same, they are not equally likely.
