Agroup of people were surveyed, and the data about their age and whether they have an iron deficiency was recorded in the two-way frequency table. based on the data in the table, the probability of randomly choosing a person who has iron deficiency and is less than 20 years old is 1.) . the probability of randomly choosing a person who does not have iron deficiency and is more than 20 years old is 2.) . chooses for #1 = 1-a.) 0.14 1-b.) 0.27 1-c.) 0.4 chooses for #2 = 2-a.) 0.15 2-b.) 0.23 2-c.) 0.3

1-A.) 0.14

2-C.) 0.3

Step-by-step explanation:

1.) The number of persons who have iron deficiency and is less than 20 years old  =41

The total number of persons surveyed = 3000

Thus, the probability of randomly choosing a person who has iron deficiency and is less than 20 years old

Hence, the  probability of randomly choosing a person who has iron deficiency and is less than 20 years old = 0.14

2.) The number of persons who do not have iron deficiency and is more than 20 years old  =43+46=89

Thus, the probability of randomly choosing a person who do not have iron deficiency and is more than 20 years old

Hence, the probability of randomly choosing a person who do not have iron deficiency and is more than 20 years old =0.3
