Viefleur [7K]

Answer:

415,000

Step-by-step explanation:

First, find the decimal equivalent of 125%. To do this, divide 125 by 100 or move two decimal places to the right: 125/100 = 1.25

Now multiply the amount of cars sold last year, 332,000, by the percentage decimal, 1.25: 332,000 x 1.25 = 415,000

A binomial experiment consists of 14 trials. The probability of success on trial 7 is 0.84. What is the probability of failure o

r-ruslan [8.4K]

Answer:

The probability of failure of trial 11 is $q = 0.16$

Step-by-step explanation:

Generally one the attributes of a binomial experiment is that the probability of success and failure is constant every trial so given from the question that the probability of success is 0.84 for trial 7 , then the probability of failure of trial 7 will be evaluated as

$q = 1 - 0.84$

=> $q = 0.16$

And from the attribute stated above the probability of failure of trial 11 is $q = 0.16$
