25 students in a high school health class are asked to write down what foods they ate last week. Of the 25
students, 14 write steak, 6 write chicken, and 5 write both steak and chicken. Using this information, answer
each of the following questions.
Let S be the event that a randomly selected student writes steak and C be the event that a randomly selected
student writes chicken.
What is P(S), the probability that a student writes steak?
What is P(C), the probability that a student writes chicken?
What is P(S and C), the probability that a student writes steak and chicken?
What is P(S or C), the probability that a student writes steak or chicken?

Hi there...
The funny thing is that you have all the answers right in front of you.
If you find the text confusing, just write down all the individual numbers separately on a list like the following...
Students-Total = 25
Wrote "Steak" = 14
Wrote "Chicken" = 6
Wrote both = 5
From there the answers are very obvious.
I hope that helped...
Kind regards...
