I have the answer in the back of my book to this problem, but could not comprehend how they came up with this answer, any clarification is highly appreciated:

local newspaper polls 400 voters in an attempt to predict whether the budget will pass. suppose that the badget actually has the support of 52% of the voters. what is the probability the newspapers's sample will lead them to predict defeat?

their answer was 0.212

i wonder how is the probability that i need tocalculate: is it the 48% who do not support the budget?

thanks.
