In an experiment, 43% of lab mice cells exposed to chemically produced cat Mups responded positively (i.e., recognized the danger of the lurking predator). Consider a sample of 100 lab mice cells, each exposed to chemically produced cat Mups. Let x represent the number of cells that respond positively. Complete parts a through d below.

a. are two

b. is one

c. are many

c) The probability of each possible outcome ________  for each trial, (a. or b.)

a. is the same

b. is different

d) and the trials are all

a. related.
