let n be the number of times letter be found (1800), p be the success rate (0.068), and q be the failure rate (1 - 0.068 = 0.932)
mean = np = 1800 x 0.068 = 122.4
standard deviation = √(npq) = √(1800 x 0.068 x 0.932) = 10.6807414
N.O = 4
N is midpoint of M.0
Meaning M.N also has to be 4
4+4= 8
N.P = 6
0.P = 2
8+ 2 = 10
|-8| - (5 + 2)2
8-(7)2
8-14= -6
Follow order of operations
First u have to find the square root for the number and then answer all of the root question then u have to find the angels
-8.7 is the answer. hope this helps
