P( satisfied )= (Round to three decimal places as needed.) (b) If a survey participant is selected at random, what is the probability that he or she is a junior? P (junior) = (Round to three decimal places as needed.) (c) If a survey participant is selected at random, what is the probability that he or she is satisfied and a junior? P( satisfied and junior )= (Round to three decimal places as needed.) (d) If a survey participant is selected at random, what is the probability that he or she is satisfied or a junior? P( satisfied or junior )= (Round to three decimal places as needed.)

(a) If a survey participant is selected at random, what is the probability that he or she is satisfied with student government?
$P($ satisfied $)=$ $\square$
(Round to three decimal places as needed.)
(b) If a survey participant is selected at random, what is the probability that he or she is a junior?
P (junior) $=\square$ $\square$
(Round to three decimal places as needed.)
(c) If a survey participant is selected at random, what is the probability that he or she is satisfied and a junior?
$P($ satisfied and junior $)=$ $\square$
(Round to three decimal places as needed.)
(d) If a survey participant is selected at random, what is the probability that he or she is satisfied or a junior?
$\mathrm{P}($ satisfied or junior $)=$ $\square$
(Round to three decimal places as needed.)
