Find p(not a 1).
x 1 2 3 4
p(x) 0.30 0.40 0.15 0.15
a. 0.85
b. 0.70
c. 0.15
d. 0.30

P ( not a 1 ) = ?
P ( a 1 ) = 0.30
P ( not a 1 ) = 1 - 0.30 = 0.70
B ) 0.70
Thank you.

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
