See a solution process below:

First, there are #3# numbers (6, 7, 8) greater than #5# on a spinner numbered #1#-#8# (1, 2, 3, 4, 5, 6, 7, 8). Therefore, there is a:

#3/8# probability of spinning a number greater than #5#.

However, there is only a 50-50 or #1/2# chance of tossing a tail on a coin.

Therefore the probability of spinning a number greater than #5# AND tossing a tail is:

#3/8 xx 1/2 = 3/16#

Or

#3# in #16#

Or

18.75%
