Answer:
The sum of the first 5 terms is -244
Step-by-step explanation:
To calculate the sum of the geometric series, we need the first term, the common ratio and the number of terms we would like to sum.
The first term here is -4
The common ratio is T2/T1 or T3/T2 = 12/-4 = -3
number of terms n = 5
The formula to use is;
Sn = a(1-r^n)/(1-r)
Plugging these values, we have;
Sn = -4(1-(-3)^5)/(1-(-3))
Sn = -4(1+243)/4 = -1(244) = -244
The 3rd one because the rest you would have to distribute them and for the 3rd one it’s the same
Total = 12 marbles
6 brown marbles but h<span>alf of the brown marbles are made of glass
so brown and made of glass = 3
</span><span>probability that it is a brown, glass marble = 3/12 = 1/4
answer
1/4</span>
