Answer:
[tex]\frac{2}{5}[/tex]
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 = [tex]\frac{10}{40}[/tex]
No. of times 5 occured = 6
So, probability of getting 5 = [tex]\frac{6}{40}[/tex]
So, probability of rolling a 1 or a 5 = [tex]\frac{10}{40}+\frac{6}{40}[/tex]
= [tex]\frac{16}{40}[/tex]
= [tex]\frac{2}{5}[/tex]
Hence the experimental probability of rollin 1 or a 5 is [tex]\frac{2}{5}[/tex].
