A pair of dice is rolled. If the outcome is a doublet, a coin is tossed. Determine the total number of elementary events associated to this experiment.

Answer :

Given: A pair of dice is rolled , a coin is tossed.


To Find: Write the sample space for the given experiment.


Explanation: A pair of dice is rolled,


Then, No. of elementary events are 62=36


Now, If outcomes is doublet means (1, 1)(2, 2)(3, 3)(4, 4)(5, 5)(6, 6), then a coin is tossed.


If coin is tossed then no. of sample spaces is 2


So, The total no. of elementary events including doublet = 6×2=12


Thus, The Total number of elementary events are 30+12 =42


Hence, 42 events will occur for this experiments.
