a. n = 10, x = 8, p = 0.3
b. n = 8, x = 7, p = 0.95

You can put this solution on YOUR website! If x is a binomial random variable, use the binomial table to determine the probability of x for each of the following:
a. n = 10, x = 8, p = 0.3
In this table.
http://www.algebra.com/tutors/faq.mpl
the letter "r" is used in place of your "x"
scroll down to find 10 in the far left column for n
In the next column under r find 8.
Go to the column for .30 (the 7th column right of the
vertical line.)
Read the number .001
b. n = 8, x = 7, p = 0.95
scroll down to find 8 in the far left column for n
In the next column under r find 7.
Go to the column for .95 (the last column on the right.)
Read the number .279
