Giant-pair fraction in an instantaneous stellar burst
= Giant-pair fraction in an instantaneous stellar burst
{title2=$\Pr(GG\mid t)=g(t)^2$}
In an instantaneous burst all binary components have a fixed common age. If the initial component masses are independent, the <probability> of two <red giants> is the square of the individual giant <probability> at that age. This need not equal the age-averaged pair fraction in a continuously forming population.
