Answer:
0.25
Step-by-step explanation:
We are given that Rob created the Venn Diagram shown below which gives us,
The probability of teenagers who like to eat hot dogs = P(HD) = 0.3
The probability of teenagers who like to eat hamburger = P(HB) 0.4
The probability of teenagers who like to eat both = P( HD ∩ HB ) =0.1
The probability of teenagers who like to eat none = 0.2
It is required to find the probability that a teenager eats hot dogs when it is given that he/she eats hamburger i.e. P( HD | HB ).
Now, we know that the probability that an event B occurs given that event A has already occurred is given by,
So,
i.e.
i.e.
Hence, the probability that a teenager eats hot dogs when it is given that he/she eats hamburger is 0.25.

Answer:
<h2><u><em>
112in²</em></u></h2>
Step-by-step explanation:
10 * 10 and you find the square, add (6 * 4) : 2 (triangle) and you have the total area
10 * 10 = 100
(6 * 4) : 2 = 12
100 + 12 = 112in²
