Answer:
11.8
Step-by-step explanation:
I think it is subtracting fractions.
First you turn the fractions into decimals then subtract it. After, you turn the decimal to a fraction but i am having a hard time doing that... the decimals by the way is 12.5 and 0.7 according to converters
Answer:
v=πr^2h
v/πr^2=h
Step-by-step explanation:
Answer:
And we can find the individual probabilities like this:
And adding we got:

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 to find this probability:
And we can find the individual probabilities like this:
And adding we got:
