Answer:

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

Explanation:

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
