Pink and orange combined make a light red-orange color. Pink is made of red and white, while orange is made of red and yellow. A new color made from pink and orange could be broken down to be 2 parts red, 1 part white, and one part yellow. This is called a red-orange tint, or a very warm light orange.
You cannot make pink from two primary colors. You need one primary color (red) and one neutral color (white.) The color pink is to the color red what the color "light blue" is to blue. This means that pink could be thought of as "light red." Adding a second primary color into the mix would not make red any lighter, it would make it look more orange or more purple.
