Unformatted text preview: (a) What is the probability that the student reads at least one of the two newspapers? Let T = event that student reads the Tribune, M = event that student reads the Mustang Daily. Then, P ( T ) = 0 . 60 , P ( M ) = 0 . 80 , and P ( T ∩ M ) = 0 . 50. P ( T ∪ M ) = 0 . 6 + 0 . 8. 5 = 0 . 90 (b) What is the probability that the student reads neither paper? P ( T ∪ M ) C = 1. 9 = 0 . 10 (c) What is the probability that the student reads exactly one of the two newspapers? P ( T ∩ M C ) + P ( T C ∩ M ) = (0 . 6. 5) + (0 . 8. 5) = 0 . 40 OR P ( T ∪ M )P ( T ∩ M ) = 0 . 9. 5 = 0 . 40 3. Beethoven wrote 9 symphonies and Mozart wrote 27 piano concertos. If a university radio station announcer wishes to ﬁrst play a Beethoven symphony and then a Mozart concerto, in how many ways can this be done? 9 × 27 = 243 ways...
