Answer:

And we can use the probability mas function and 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".
Solution to the problem
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:
And we want this probability:

And we can use the probability mas function and we got:
Answer:
Step-by-step explanation:
We have given,

Take out 2 from the left side and we multiply both side by 2 we get:
Next,
subtract both sides by 7, we get :

Now we divide both sides by 4, to get x.
So we get, x = 8
