Navigation Bar HTML+CSS

Question

Basically I would like to change my navigation bar so that the first child will float to the left and the last child to the right, leaving the 3 other list items in the center. I have a feeling that the answer lies somewhere between flex-box and creating a table! I'm unsure if there is a better way to do this.

HTML:

<nav role="navigation">
        <ul>
            <li><a href="#">Random</a></li>
            <li><a href="#">Account Summary</a></li>
            <li><a href="#">Statements</a></li>
            <li><a href="#">Payments & Transfers</a></li>
            <li><a href="#">Random</a></li>
        </ul>
    </nav>

CSS:

  nav {
    width:100%;
}

nav ul{
    font-size: 1.4em;
    color: white;
    margin:auto;
    text-align: center;
    padding:30px;
    border-top: 1px solid #1C1B1A;
    background-color: rgb(63,67,120);
    /* Old browsers */
    /* IE9 SVG, needs conditional override of 'filter' to 'none' */

    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#3f4378', endColorstr='#20234a',GradientType=0 ); /* IE6-8 */
}

nav ul li{
    width:100%;
    display: inline;
    text-decoration: none;
    margin: auto;

Answer 1

Try this:

nav ul li:first-child a{
    float:left;
}  
nav ul li:last-child a{
    float:right;

}

If you want to keep the design:

nav ul li:first-child a{
    float:left;
   margin-top:-30px;
}  
nav ul li:last-child a{
    float: right;
  margin-top:-30px;
}
