Amit is going to guess on all 202020 questions of his multiple-choice test. Each question on the test has 444 answer options, and only one is correct. What is the best prediction for the number of questions that Amit will answer correctly?

5 questions

Step-by-step explanation:

If there are four options and only one is correct. I.e option a, b ,c and d

Let us first calculate the probability of answering on one question.

The probability of getting one question correctly will be

1 /4

Number of questions she will get correctly among the 20 questions will be

1/4 × 20 = 5 questions

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

they go with it happens or they mite give a chance?
