The 2nd number line model represents 1 + ( -3 ).
The probability that exactly 128 flights are on time is 88.27% and the probability that atleast 1 flight is on time is 0.022.
Given that the chances of reaching the flight on time be 88%.
We are required to find the probability that exactly 128 flights are on time, atlleast 1 flight on time.
Probability is basically the calculation of likeliness of happening an event among all the events possible. It lies between 0 and 1.
Probability=Number of items/Total items.
It cannot be negative.
Probability that the flight will be on time if one flight is selected=0.88
Probability that exactly 128 flights are on time=
128=1145*P/100
P=12800/145
P=88.27%
b) Atleast 1 flight is on time
=(
+
)/128
=(0.12+128*0.88*0.245)/128
=(0.12+2.575)/128
=0.022
Hence the probability that exactly 128 flights are on time is 88.27% and the probability that atleast 1 flight is on time is 0.022.
