The table shows the distribution of goals scored by 25 teams in a football competition. Calculate the probability that a team selected at randon scored either 4 or 7 goals.
A. \(\frac{9}{25}\) B. \(\frac{1}{5}\) C. \(\frac{6}{25}\) D. \(\frac{2}{5}\)
Correct Answer: A
Explanation
Prob. (team scored 4 goals) = Prob. (team scored 7 goals) = \(\frac{3}{25}\) Hence, probability that a team selected at random scored either 4 or 7 goals; = \(\frac{6}{25} + \frac{3}{25}\) = \(\frac{9}{25}\)
