ind the indicated probability. Round to three decimal places.

An airline estimates that 90% of people booked on their flights actually show up. If the airline books 64 people on a flight for which the maximum number is 62, what is the probability that the number of people who show up will exceed the capacity of the plane?

Question 15 options:

A) 0.008
B) 0.010
C) 0.001
D) 0.039

Solution

Note that P(at least x) = 1 - P(at most x - 1).          
          
Using a cumulative binomial distribution table or technology, matching          
          
n = number of trials =    64      
p = the probability of a success =    0.9      
x = our critical value of successes =    63      
          
Then the cumulative probability of P(at most x - 1) from a table/technology is          
          
P(at most   62   ) =    0.99043685
          
Thus, the probability of at least   63   successes is  
          
P(at least   63   ) =    0.00956315

The closest here is

OPTION A: 0.008 [ANSWER]
