Answer:
Probability of getting a number which is not 2 = 7/8
Step-by-step explanation:
Given;
Total number of faces = 8
Number of face with 2 = 1
Number of face with 3 = 2
Number of face with 4 = 1
Number of face with 7 = 3
Number of face with 9 = 1
Find:
Probability of getting a number which is not 2
Computation:
Probability of not an event = 1 - [Number of favourable outcomes / Total number of outcomes]
Probability of getting a number which is not 2 = 1 - [1/8]
Probability of getting a number which is not 2 = [8-1] / 8
Probability of getting a number which is not 2 = 7/8
1 - 1/5 = 5/5 - 1/5 = 4/5
4/5 - 1/5 = 3/5
3/5 - 1/5 = 2/5
2/5 - 1/5 = 1/5
1/5 - 1/5 = 0
We can subtract 1/5 from 1 a total of 5 times, so 1 ÷ 1/5 = 5.
