If 80% of scheduled flights actually take place and cancellations are independent events, what is the probability that 3 separat
Mekhanik [1.2K]

 

We are given that 80% of scheduled flights really take place, therefore this means that:

Probability of flying = 80% = 0.80

 

Now in statistics class, we know that the probability of two or more independent events to occur is simply equivalent to the product of their probabilities, or mathematically written as: (P = Probability)

total P = P1 * P2 * P3 *...

 

In this case, since we are to find for the probability that 3 independent flights will occur, therefore the total probability assuming equal probabilities to fly is:

total probability = 0.80 * 0.80* 0.80

total probability = 0.512

or

total probability = 51.20%

 

This means that there is only a 51.20% chance for 3 flights to occur.

Can a triangle have sides with the given lengths? Explain.<br> a = 6 yd, b = 9 yd, c = 11 yd
RideAnS [48]

Answer:

Step-by-step explanation:

Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))

By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.
