(A)The probability that a randomly selected silver medal was awarded to Great Britain is 17/99.

Step-by-step explanation:

The table is given below:

\left|\begin{array}{l|c|c|c|c|c}  &Gold&Silver          & Bronze       &Total\\United States    &46      &    29      &          29      &         104\\China             &     38     &     27       &         23        &         88\\Russia         &        24  &        26      &          32                 &82\\Great Britain   &    29   &        17        &        19        &         65\\&&&&&\\Total                    &137     &     99     &          103      &        339\end{array}\right

                         

We calculate the probabilities given in the statements.

(A) The probability that a randomly selected silver medal was awarded to Great Britain

= 17/99

(B)The probability that a randomly selected medal won by Russia was a bronze medal

=32/82

(C)The probability that a randomly selected gold medal was awarded to China

=38/137

(D)The probability that a randomly selected medal won by the United States was a silver medal

=29/104

We can see that only the first statement is true.
