There are 12 questions on a multiple -choice quiz in which each question has 5 possible answers a b c d and e . if the person guesses on each question, what's the probability of guessing correct on: Round to the nearest thousands. A) all the questions?

b) one question?

c) Two questions?

D) At least on question?

F) More than three questions?

g) What is the expected number of correct guesses?

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

1/3 + 1/5 = 8/15.

step-by-step explanation:
