Using it's concept, it is found that the probabilities are given as follows:
a.1/2, 1/9, 5/9.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 90 out of 180 individuals are children, hence the probability is given by:
p = 90/180 = 1/2.
Out of 90 adults, 60 - 50 = 10 preferred cheeseburgers, hence the probability is given by:
p = 10/90 = 1/9.
Of the 180 individuals, 90 are children, and 10 are adults who prefer cheeseburgers, hence the probability is given by:
p = 100/180 = 10/18 = 5/9.
Hence option a is correct.

Answer is 18 do you need work shown
Answer:
Hello! answer: 30
Step-by-step explanation:
Triangle area can be found be doing base × height × 1/2 or base × height ÷ 2
So...
12 × 5 = 60 60 ÷ 2 = 30 therefore the area is 30 hope that helps!
