If x is a binomial random variable with n trials and success probability p , then as n gets smaller, the distribution of x becomes

If the value of n gests smaller then the distribution of X would be more skewed, that's a property of the binomial distribution

Step-by-step explanation:

For this problem we are assumeing that the random variable X is :

If the value of n gests smaller then the distribution of X would be more skewed, that's a property of the binomial distribution and if we don't satisfy this two conditions:

Then we can't use the normal approximation

Step-by-step explanation:

9y + 12 = 4y - 10

Sub. 4y from both sides

5y + 12 = 10

Sub. 12 from both sides

5y = -2

Divide 5from both sides

y = -2/5

Substitute -2/5 into 4y - 10
