The probability on the spinner for each section is 0.2 or written a 2 in 5 ( 1 divided by 5 as it has equal sections)
The probability for landing the green side of the dice is 1 in 6
In order to obtain the combined probability you must multiply both together
(1 in 6) * (2 in 5) = (2 in 30 which can be written as 0.066
