(a) We have ratio of the ships $A, B$ and $C$ for arriving safely are $2 : 5, 3 : 7$ and $6 : 11$ respectively.

$	herefore $ The probability of ship $A$ for arriving safely $ = \frac{2}{{2 + 5}} = \frac{2}{7}$

Similarly, for $B = \frac{3}{{3 + 7}} = \frac{3}{{10}}$ and

for $C$ = $\frac{6}{{6 + 11}} = \frac{6}{{17}}$

$	herefore $ Probability of all the ships for arriving safely

$= \frac{2}{7} 	imes \frac{3}{{10}} 	imes \frac{6}{{17}} = \frac{{18}}{{595}}$.

Three ships $A, B$ and $C$ sail from England to India. If the ratio of their arriving safely are $2 : 5, 3 : 7$ and $6 : 11$ respectively then the probability of all the ships for arriving safely is
