Answer:

#P(1 T)=3/8#

Explanation:

If we do this from first principals.

List all the possible outcomes for tossing a coin three times.

#H=" head, T=" tail"#

on three tosses:

#HHH#

#color(blue)(HHT)#
#color(blue)(HTH)#
#color(blue)(THH)#

#HT T#
#THT#
#T TH#

#T T T#

8 possibilities in all

if we look at the list there three ways of obtaining one tail

#P(1 T)=3/8#

Other ways of doing this would involve the laws of probability or Binomial distribution.
