The probability that the first three cases are all pink is  0.049.

<h3>What is the probability that the first three cases are all pink?</h3>

Probability is used to determine how likely it is for an event to happen. The chances of the event happening lies between 0 and 1.

Probability that the first three cases are all pink = (30/80) X (29/79) X (28/78) = 0.049

An airline knows that on average about 5 percent of the people who make reservations on a certain flight will not show up. Conse
kolbaska11 [484]

Answer:

Probability that there will be a seat available for every passenger who shows up is 50/50 or 49/50

Step-by-step explanation:

Since it is known that 5percent of people who make reservations would not show up.

Therefore 5% of 52 sold ticket is

5/100 x 52 = 2.6

That is 2 or 3 people who make reservations would not show up.

Which means 52 - 2 or 52 - 3 people would show up

50 or 49 people would show up

Since the flight can hold just 50 people

The probability that everyone that shows up would have a seat is therefore =

50/ 50 or 49/50
