Each respondent was given a score, from 1 to 15, on his or her knowledge of the COFLU-20. A score from 1 to 7 was considered to indicate ‘poor’ knowledge, 8 to 11 indicated ‘satisfactory’ knowledge and 12 to 15 indicated good knowledge. Table 2 below shows the knowledge level of respondents, by age group. Table 2 Age Group Knowledge Level Total Poor Satisfactory Good 18 - 25 33 16 13 62 26 - 34 30 18 12 60 35 - 44 29 14 12 55 45 - 54 36 16 18 70 55 - 75 17 14 22 53 Total 145 78 77 300 (c) Using Table 2, assist the researcher to calculate the probability that a randomly selected respondent: (i) is below 35 years of age and has good knowledge of the COFLU-20 (ii) is below 35 years of age or has good knowledge of the COFLU-20
