#4# in #5#

"The odds of" refers to the method of writing a probability as
#x# in #y#.

the probability of raining tomorrow is 80%
#=80/100#
#=4/5#

Therefore, the odds of rain tomorrow is #4# to #1#.

The odds of rain are #4:1#.

Convert the probability percentage to a fraction:

#80% -> 4/5#

Any fraction will do. Now take the number on bottom and subtract the number on top:

#5-4 = 1#

The number on top #4# is the first number in the odds expression, and this new #1# is the second number.

#"Probability = 80% " => " Odds = 4:1"#

This odds expression means that, for every 4 rainy days, we expect to get 1 non-rainy day (5 days total).
