(a) what is the probability that celia is first in line or felicity is first in line? (b) what is the probability that celia is first in line or felicity is last in line? (c) what is the probability that celia is not next to felicity in line? (d) what is the probability that hubert is next to celia or felicity in line? (e) what is the probability that hubert is not next to either celia or felicity in line?
