Question 7

Symbols in binomial probability

Answer 7

n= number of trials
r= number of successes
a (q) = probability of failure
b (p) = probability of success

Question 8

Conditions of binomial distribution.

Answer 8

1: The number of trials is fixed.
2: Each observation is independent.
3: There can only be one of two outcomes (“success” or “failure”).
4: The probability of “success” is the same for each outcome.
