Answer
$P(8 \leq x \leq 10)$ $= 0.16$
Interpretation: The probability that at 8 to 10 (inclusive) flights are on time is 0.16. If we carry out 100 trials of this experiment, we expect that approximately 16 trials will result in 8 to 10 (inclusive) flights being on time.
Work Step by Step
$P(8 \leq x \leq 10)$
$ = P(x = 8) + P(x=9) + P(x = 10)$
$= 0.0138 + 0.0430 + 0.1032$
$= 0.16$
Interpretation: The probability that at 8 to 10 (inclusive) flights are on time is 0.16. If we carry out 100 trials of this experiment, we expect that approximately 16 trials will result in 8 to 10 (inclusive) flights being on time.
