The probability of students

Question

70% like chocolate ice cream, 40% like strawberry ice cream, and 30% like both. If a student is randomly selected what is the probability that they like chocolate or strawberry but not both

Answer 1

Allison,

 

70% like chocolate

40% like strawberry

30% like both

 

Students who like only chocolate = (70-30) = 40%

Students who like only strawberry = (40-30) = 10%

 

Probability that a random student picked likes chocolate or strawberry = 40% + 10% = 50%
