1)
Medals tally for 18 countries:
x: 1, 2, 3, 3, 4, 9, 9, 11, 11, 11, 14, 14, 19, 22, 23, 24, 25, 29
number of data points (n) = 18

mean (x) = sum(x)/n = (1+2+3+3+4+9+9+11+11+11+14+14+19+22+23+24+25+29)/18 = 13 ...

Solution Summary

In first problem mean mode and median of given data is estimated. In second problem, binomial probaility distribution concept is used.
