Conditional formatting based on if contains a specific symbol

I am creating a tutor master.

some courses are one day others are 2 days.

a = month

b = which day of week

c = dates of course

d = start and end times of course

f = lead tutor day 1

g = support tutor day 1

h = lead tutor day 2

i = support tutor day 2

if its a 2 day course b and c cells for that row will contain an & symbol

so if & is found in column c of that row i want to use the existing conditional formating rules. but if & is not present in column c of that row then format column h and i in that row to show there is no day 2.

if column b in a row contains the word cancelled i want all cells on that row column b - q to have a specific formatting to indicate the course on that dates is cancelled.

how do i acheive this.
