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.


a. What is P(S) the probability that a student writes steak?

b. What is P(C), the probability that a student writes chicken?

c. What is P(S∪ C), the probability that a student writes steak or chicken?

d. What is P(S∩C), the probability that a student writes steak and chicken?

a. P(S)= 19/25

b. P(C)= 11/25

c. P(S union C)= 20/25=4/5

d. P(S intersect C)= 5/25= 1/5

 

 

Hope it helps!
