Question 831986: Albert rolls a number cube and records the results in the table. Find the experimental probabilities.
Number 1 2 3 4 5 6
# of rolls 11 15 8 15 11 6
a) P(2)= 15?
b) P(1or5)= ???
C) P(not a 5)=???
d) P(6)=6?
I tried a)and d) I am not sure if they are right and I think b) might be 11 but I am really not sure and need help to solve c)
Please help. My parents are not able to help with this.

Probabilities are outcomes that you're interested in divided by total outcomes.
Probabilities are always at least zero and at most 1.
Albert rolled the cube times or times.
a) P(2)=
b) P(1 or 5)=P(1)+P(5)=
c) P(not a 5) means P(everything but a 5)=
You could also get it by summing all the probabilities of the other numbers,
P(not a 5)=P(1)+P(2)+P(3)+P(4)+P(6)=
d) P(6)=6/66=
