Question
Consider 5 independent Bernoulli′s trials each with probability of success p. If the probability of at least one failure is greater than or equal to
, then p lies in the interval
, then p lies in the intervalOptions
A.

B.

C.

D.

Solution
n = 5
Success = p
Failure = q
P (at least one failure) ≥
1 - P (no failure) ≥
1 - P( x = 5) ≥
1 - 5C5 p5 ≥
- p5 ≥ -


Success = p
Failure = q
P (at least one failure) ≥

1 - P (no failure) ≥
1 - P( x = 5) ≥
1 - 5C5 p5 ≥
- p5 ≥ -
