1. Consider the pyramid ABCDE in the figure 1 attached:
Each side of the square base equals
(units)
Area of 1 lateral side of pyramid ABCDE is
so the total lateral area is
(units squared)
and the total surface area is
(units squared)
2. Now consider the second figure KLMNP, Sydney's pyramid:
The lateral area is
so the total area of the second pyramid is
So 2 things can be said about the areas:
i) the lateral area of Sydney's pyramid is
times larger than the lateral area of the original pyramid.
ii) The total area of Sydney's pyramid is
units squared larger than the total area of the original pyramid.
Each side of the square base equals
Area of 1 lateral side of pyramid ABCDE is
so the total lateral area is

Answer: LIKLEY
Step-by-step explanation:
Formula : Probability
A standard cube has six numbers on it (1,2,3,4,5 and 6).
P( NOT 6) =
We know that when the probability of any event lies between 0.5 and 1then the event is said to be likely to happen.
Since , P(not 6)=0.8333 which lies between 0 and 0.5.
That means, it is<em> likely</em> to happen.
Note :
When probability of having A = 0 , we call A as uncertain event.
When probability of having A = 1 , we call A as certain event.
When probability of having A = 0.5 , we call A as equally likely event.
When probability of having A lies between 0 and 0.5 , we call A as unlikely event.
When probability of having A lies between 0.5 and 1 , we call A as likely event.
