Assume that random guesses are made for 3 multiple-choice questions on a test with

2 choices for each question, so that there are n

=

3 trials, each with probability of success (correct) given by p

=

0.50. Find the probability of no correct answers.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
