What does the expected value of a binomial distribution with n trials tell you?

The expected value of a binomial distribution with n trials tell us about the the average number of successes

Step-by-step explanation:

A binomial distribution is a frequency distribution of the possible number of successful outcomes in a given number of trials such that there is the same probability of success of each of the outcome.

For n trials with probability of success of each outcome as p, expected value of a binomial distribution  is given by .

If we toss 200 coins, and X is the number of heads, the expected value of X is 100= (1/2)200.

So, basically the expected value of a binomial distribution with n trials tell us about the the average number of successes .

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
