Answer:
And we can find the individual probabilities using the probability mass function and we got:
And replacing we got:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Solution to the problem
For this case we want this probability:
And we can use the complement rule and we got:
And we can find the individual probabilities using the probability mass function and we got:
And replacing we got:
Answer:
Ok, this is really simple. We just need to add!
Step-by-step explanation:
We know that Tiff read 115 pages.
We know thef there are 152 pages left.
When we add we get 267.
There are 267 pages in the book.

Answer:
60 minutes or 1 hour
Step-by-step explanation:
Set x as the amount of time she spends riding the bus
75 = time on bus + time on train
She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x
75 = x + 4x
75 = 5x
x = 15 minutes on the bus
Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour
Yes it is easy what u all have to do is to check that by which number or fraction is the equation being divided or multiplied, here in a it is multiplied by 10 so it will be 2
in b it is being divided by 100 or multiplied by 1/100 both are same so b will be 340 in first blank and in second it will be 0.034
in c it is being divided by 10 so in first blank it will be 85700 and in second it will be 857 and in third it will be 0.857
in d it is being multiplied by 10 so in first blank it will be 44400 in second it will be 444000 and in third it will be 4440000
in e it is... in the first blank it will be multiplied by 1/100 and then in second blank it will be multiplied by 100 so first blank will be 0.095 and second will be 9500000 and third blank will be 950000000
