With what I don't see a question
Answer: 0.884736
Step-by-step explanation:
Given: The proportion of all air travel departs on time: p= 0.96
Total flights : n= 3
Let x be the number of flights on time.
As there are two cases either flight on time or not, so it is a binomial case.
Binomial distribution formula:
The probability that all of them depart on time =
The probability that all of them depart on time = 0.884736
The given expression is
Here P represents Permutation and C represents Combination
Thus, the given expression can be rewritten as:
Therefore, for the given expression , it's value is 5010
Maybe use photo math i guess
