Step-by-step explanation:
Given :
Outcome Number of times outcome occurred
1 10
2 6
3 4
4 8
5 6
6 6
To find: What is the experimental probability of rolling a 1 or a 5?
Solution:
No. of times dice rolled = 10+6+4+8+6+6=40
No. of times 1 occured = 10
So, probability of getting 1 =
No. of times 5 occured = 6
So, probability of getting 5 =
So, probability of rolling a 1 or a 5 =
=
=
Hence the experimental probability of rollin 1 or a 5 is .
