Need help with this question. Thanks

A random sample of adults in some country (18 years and older) was asked, "When you see an ad emphasizing that a product is "Made in our country," are you more likely to buy it, less likely to buy it, or neither more nor less likely to buy it?" The results of the survey, by age group, are presented in the following contingency table. Complete parts (a) through (b). Purchase likelihood

18-34 35-44 45-5455+Total

More likely202 372 376 410 1360

Less likely 29 5221268

Neither more nor less likely 296 201 155 141 793

Total 527 578 553563 2221

(a) What is the probability that a randomly selected individual is at least 55 years of age, given the individual is less likely to buy a product emphasized as "Made in our country"?

(b) What is the probability that a randomly selected individual is less likely to buy a product emphasized as "Made in our country," given the individual is at least 55 years of age?
