Answer:
Step-by-step explanation:
Let A be the event that the sum is 7 and and B be the event that the sum is 11 .
When two pair of dices rolled the total number of outcomes =
The sample space of event A ={(1,6), (6,1), (5,2), (2,5), (4,3), (3,4)}
Thus n(A)= 6
The sample space of event B = {(5,6), (6,5)}
n(B)=2
Since , both the events are independent , then the required probability is given by :-
Hence, the required probability =
Answer:
(x+9)(3x+27)
Step-by-step explanation:
3x^2+54x+243 (243×3=729, Product=729, Sum=54) [27+27=54, 27×27=729]
3x^2+27x+27x+243
3x(x+9)+27(x+9)
=(x+9)(3x+27)
