A Department of transportation report about air travel that nationwide, 76% of all flights are on time. In a sample of 12 flights, what is the probability that 3 flights will be late?

The probability of 3 flights are late is 0.25.

Step-by-step explanation:

Total number of flights = 12

Flights on time = 76 % = 0.76 x 12 = 9.12 = 9

flights which are late = 24 % = 0.24 x 12 = 2.88 = 3

The probability of 3 flights are late is

P = 3/12= 1/4 =  0.25  

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
