Given:
- Five students, Adriana, Ben, Chandra, Diana, and Ernesto are competing for four spots.
- Four names are chosen at random.
To find:
Probability that Chandra will be chosen as one of the science fair participants
Answer:
- Let, the probaility of Chandra being selected be P.
- P = Number of favourable outcomes/ Total number of outcomes.
- P = No. of seats available/ No. of competitors
- P = 4/5
- P = 80%
Probability that Chandra will be chosen as one of the science fair participants = 80%
