(2,5 x 10^-10)(7 x 10^-6) = (2.5 x 7) x 10^(-10 - 6) = 17.5 x 10^-16 = 1.75 x 10^-15
Answer:
52.56% probability that eight or more of the flights will arrive on time.
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it is on time, or it is not. The probability of a flight being on time is independent from other flights. So we use the binomial probability distribution to solve this question.]
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
At a certain airport, 75% of the flights arrive on time.
This means that
A sample of 10 flights is studied.
This means that
Find the probability that eight or more of the flights will arrive on time.
In which
52.56% probability that eight or more of the flights will arrive on time.
8/12 is the same as 2/3
x/2 + x/2 = 8/12
2x/2 = 2/3
x = 2/3
another way is:
x/2 + x/2 = 8/12
x/2 + x/2 = 2/3
(2/3)/2 + (2/3)/2 = 2/3
1/3 + 1/3 = 2/3
2/3 = 2/3
The answer is points B.C.and D are on line n
