$	herefore $ Either $0$ head by $A$ and $0$ head by $B$

or $1$ head by $A$ and $1$ head by $B$

or $2$ head by $A$ and $2$ head by $B$

or $3$ head by $A$ and $3$ head by $B$

$	herefore $ Required probability

$ = \left[ {\frac{1}{8} 	imes \frac{1}{8} + \frac{3}{8} 	imes \frac{3}{8} + \frac{3}{8} 	imes \frac{3}{8} + \frac{1}{8} 	imes \frac{1}{8}} ight] = \frac{5}{{16}}$.
