Question

The table below shows a sample of the distribution of income per age group for clients that have bought an iPad in 2019

Age	<$25,000	$25,000-50,000	>$50,000
<25 years old	5%	10%	4%
25-35 years old	5%	20%	12%
36-55 years old	7%	15%	9%
>55 years old	3%	5%	5%

Determine the following probabilities:

4) P (income more than $25,000) =

5) P P (Income less than $50,000) =

6) P (Age more than 55 years old) =

7) P (Age less than 36 years old) =

8) P (Age between 25-55 OR income more than $50,000)

9) P (Age between 25-55 AND income more than $50,000)

10) P (Income less than $25,000 and age between 25-55 years old)

11) P (Age under 55 years and income less than $50,000)

Answer 1

(there are more than 4 parts, as per policy i am answering first 4 parts)

4.

P (income more than $25,000) = sum of percentage in table which are under the 2nd and 3rd column

= 0.10+0.20+0.15+0.05 + 0.04+0.12+0.09+0.05

= 0.80

5.

P (Income less than $50,000) = sum of percentage in table which are under the 2nd and 1st column

= 0.10+0.20+0.15+0.05 + 0.05+0.05+0.07+0.03

= 0.70

6.

P (Age more than 55 years old) = sum of percentage in table which are in 4th row

= 0.03+0.05+0.03

= 0.11

7.

P (Age less than 36 years old) = sum of percentage in table which are in 1st and 2nd row

= 0.05+0.10+0.04+0.05+0.20+0.12

= 0.56
