the picture in the attached figure
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
P=size of the event space/size of the sample space
step 1
find the probability of rolling a 4
size of the sample size=6
size of the event space=1
P=1/6
step 2
find the probability of spinning green
size of the sample size=4
size of the event space=1
P=1/4
step 3
Find the probability of spinning green and rolling a 4
P=(1/4)*(1/6)----> 1/24----> 0.0417----> 4.17%
the answer is
4.17%
