The slope is 5/3 and the y-intercept is 2. You will have to draw the graph yourself.

it is C(9,4) or "9choose4" = 9!/(4!5!) If you are studying this level of probability, then you must be familiar with that concept.

Ok, let's just consider one of the possible outcomes. S = success, F = failure SSFFSFFFS (4 successes, 5 failures) the prob of that specific event is .6 x .6 x .4 x .4 x .6 x .4 x .4 x .4 x .6 = (.6)^4 x (.4)^5 but the SSFFSFFFS can be arranged in 126 ways, so .....

depends on the calculator. On mine, which is a Casio, it is shown as nCr On many calculators it is paired with nPr which is defined as n!/(n-r)! and is used in permutations. If you cannot find it on your calculator, look for the factorial key ! , which is found on most ...

Prob(success) + prob(failure) = 1 so if prob(success) = .6 then prob(failure) = 1 - .6 = .4
