A test has 6 multiple choice questions, each with 4 alternatives. What is the probability of guessing 5 or more questions correc

ira [324]

Answer:

0.0009765625‬

Step-by-step explanation:

Each multiple choice question has 4 equally likely alternatives.

Hence, probability of guessing the right answer for 1 question is $\frac{1}{4}$ = 0.25

Hence, probability of guessing the wrong answer is $\frac{1}{4}$ = 0.75

The probability of guessing 5 or more questions correctly = probability of guessing 5 questions correctly & 1 question wrong + probability of guessing 6 questions correctly

= $\[0.25^{5}*0.75+0.25^{6}\]
$

= 0.000732421875 + 0.000244140625

= 0.0009765625‬
