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 is A

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;

= \(\frac{6}{25} + \frac{3}{25}\)

= \(\frac{9}{25}\)
