Plots going to the wrong page [duplicate]

Question

Keeping tables/figures close to where they are mentioned

In the end of a section, I added two plots and. So, I finished this section and started a new one. However, this new section appears before the plots. To illustrate (apologies for non-necessary packages because I don't know which is necessary):

\documentclass{article}
\usepackage{amsmath} 
\usepackage{amssymb}
\usepackage{natbib} 
\usepackage{graphicx} 
\usepackage{epstopdf}
\usepackage{url}
\usepackage[titletoc]{appendix}
\usepackage{eurosym}
\usepackage{listings}
 \usepackage{setspace}
\usepackage{float}
\usepackage{booktabs}
\usepackage{pdfpages}
\usepackage{array}
\begin{document}

 \section{One}

     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 \begin{figure}[p]
\centering
\includegraphics[scale=0.51]{bp1.pdf}
 \caption{Observed choice probabilities versus fitted  choice probabilities generated    by logit model using regression coefficients derived from TTO data}
 \label{bp9}
 \includegraphics[scale=0.51]{bp2.pdf}
  \caption{Observed choice probabilities versus fitted choice probabilities generated     by probit model using regression coefficients derived from TTO data}
 \label{bp10}
 \end{figure}


 \section{Two}

  cccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc
  cccccccccccccccccccccccccccccccccc

  \end{document}

Here is the output. Note that the plots appear on the second section whereas they were meant to be in the first section

Answer 1

you have \begin{figure}[p] which means "on an own page" and the next page is after section 2.

Use \begin{figure}[!htp]instead
