two dice are rolled simultaneously .Find the proability of getting a sum moe than 11 with full explation.
Answers
Step-by-step explanation:
Probability for rolling two dice with the six sided dots such as 1, 2, 3, 4, 5 and 6 dots in each die.
When two dice are thrown simultaneously, thus number of event can be 62 = 36 because each die has 1 to 6 number on its faces. Then the possible outcomes are shown in the above table.
(i) The outcomes (1, 1), (2, 2), (3, 3), (4, 4), (5, 5) and (6, 6) are called doublets.
(ii) The pair (1, 2) and (2, 1) are different outcomes.

Answer:
Step-by-step explanation:
s = { ( 1, 1 ) (1,2) ................................( 1, 6)
(2, 1) (2, 2) .............................( 2, 6)
......................................................(6, 6)} = 6 ² = 36
E = sum more than 11
= ( 6,6) = 1
P ( getting sum more than 11 ) = p(E) / p(S)
= 1 / 36
