Correct answer is D
Pr. (winning 100m race) = 18
Pr. (losing 100m race) = 1 - 18 = 78
Pr. (winning high jump) = 14
Pr. (losing high jump ) = 1 - 14 = 34
Pr. (winning only one) = Pr. (Winning 100m race and losing high jump) or Pr.(Losing 100m race and winning high jump)
= (18×34) + (78×14)
= 332+732
= 1032
= 516
