Answer 1

Solution:

Given the table;

(a) The probability that a person prefers to drink sprite;

Thus, the probability is;

$\frac{60}{110}=\frac{6}{11}$

(b) The probability that a person is between 21 and 40 years old;

Thus, the probability is;

$\frac{65}{110}=\frac{13}{22}$

(c) The probability that a person drinks lemonade given they are between 21 and 40;

Thus, the probability is;

$\frac{30}{110}=\frac{3}{11}$

(d) The probability that a person drinks sprite given they are under 21 years of age;

Thus, the probability is;

$\frac{25}{110}=\frac{5}{22}$
