$\frac{2}{7}$
The events are dependent because the marbles are not replaced 3 of the 7 marbles are yellow: P(yellow)=$\frac{3}{7}$ 4 of the 6 remaining marbles are red: P(red after yellow)=$\frac{4}{6}$=$\frac{2}{3}$ P(yellow then red)=P(yellow) $\times$ P(red after yellow) P(yellow then red)=$\frac{3}{7}$ $\times$ $\frac{2}{3}$ P(yellow then red)=$\frac{2}{7}$
