Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The percentage of parents that have one child under 18 in their homes is k = 15%
The percentage of parents that have two children is T = 65%
The percentage of parents that have three or more children is Y = 20%
Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as

=> 
=> 
U call it keep change change. keep 15.7. change it to subtract and change -3.45 to just 3.45 (positive not negative)
33 would round down. (30)
This is because the second 3 is smaller than 5 and when your rounding, if number your rounding is smaller then 5 you will round down
89 would round up. (90)
This is because the 9 is larger than 5 which means you would round up.

Answer:
Jon did determine the probability correctly.
Step-by-step explanation:
<em>In Jon's closet, there are a total of 24 clothes. Among those pieces of clothing, there are a total of 9 out of 24 clothes that are black. There are also 11 shirts out of 24 clothes. </em>
<em />
<em>When a probability has OR in it, it means to add.</em>
<em />
<em>11/24 plus 9/24 gives you 20/24.</em>
<em />
<em>Therefore, Jon is correct.</em>
