In a binomial distribution `B(n , p=1/4)` , if the probability of at least one success is greater than or equal to `9/(10)` , then n is greater than (1) `1/((log)_(10)^4-(log)_(10)^3)` (2) `1/((log)_(10)^4+(log)_(10)^3)` (3) `9/((log)_(10)^4-(log)_(10)^3)` (4) `4/((log)_(10)^4-(log)_(10)^3)`

`9/(log_10 4- log_10 3)`

`(1-log_10 9)/(log_10 4 - log_10 3)`

`1/(log_10 4 - log_10 3)`

`1/(log_10 4 +log_10 3)`
