Answer:
21.21%
Step-by-step explanation:
Assume that proportion of support follows normal distribution.For resulting in defeat the proportion of support should less than 0.5.Given that the proportion of support is p= 0.52.
Sample size(n)= 402
We know that standard deviation is given as

Now by putting the values

σ=0.0249
Proportion of support follows normal distribution with mean is 0.52 and standard deviation is 0.0249
We know that 
So

Z= -0.80
So P(Z<-.80) =0.2118 from standard table.
So the probability of news paper to predict defeat is 21.21%
I am 99% sure it is D. Hope this helped! : )

Anything except pi is a rational number. So 9 and 7/10 is one or it could be a whole number
Find a number that both of the denominates make the same number for example if one denominator is 1/7 and the other is 2/6 then you
2/6 * 7 = 14 over 42 then the other one would be 1/7 *6 which would be 6 over 42 you find common denominators by finding a number both of the bottom ones can equal. hope this helps
