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.

B and C hopefully I'm right
Answer:
23/12 (1 11/12)
Step-by-step explanation:
2 3/4 = 11/4 and in order to do 11/4 minus 5/6, you would have to find the LCM (Least Common Multiple). The LCM is 12. 11/4 times 3 is 33/12 and 5/6 times 2 is 10/12. 33/12 minus 10/12 is 23/12. In a mixed fraction, this would be 1 11/12.
um i would say 25 all together
