Step-by-step explanation
Probability is the ratio of number of favourable outcome to the number of total outcome.
In this question the favourable outcome is 1. The number of 1s in the set of data is 8.
The set of data given is 21 (total outcome).

∴P(1) = 8/21

Answer 2

Answer: Second option: 8/21

Solution:
P(1) = (Number of times we get 1) / (Total number of results)

Number of times we get 1 = 8
Total number of results = 21

P(1)=8/21
