An experimenter testing for extrasensory perception has five cards with pictures of a (s)tar, a (c)ircle, (w)iggly lines, a (d)dollar sign and a (h)heart. She selects two cards without placement. Outcomes in the sample space are represented by pairs such as (w,s) and (s,c). Complete parts (a)through (d).

a) How many elements are in this sample space

b) express the event "a star appears on one of the cards" as a set.

a. (s)

b. (s,c), (s,w), (s,d),(s,h)

c. (s,c,w,d,h)

d. (s,c),(s,w),(s,d),(s,h),(c,s)(w,s)(d,s),(h,s)

c) what is the probability that a star appears on oneof the cards?

d) whatis the probability that a dollar sign does not appear?
