assume that random guesses are made for 8 multiple choice questions on an SAT test, so that there are n=9 trials, each with prob
melamori03 [73]

Answer:

P(x

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

P(x

Then:

P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}

P(x\leq3)=0.0994
