When u have a larger population at hand the chances of your predictions being right are higher. So for example if he predicted a 3:1 ratio(yellow to green peas) he’d have a higher chance of seeing this ratio in a larger population than he would in a smaller one.
V (volume) = 5l
c (molar concentration or molarity) = 3 M = 1 mol/l
c = n/V, where n is the number of moles or amount of substance
So: n = c * V = 3 mol/l * 5l = 15 moles
