ind the probability of answering the two multiple choice questions correctly if random guesses are made. Assume the questions ea

algol13

Answer: a. 0.04

Step-by-step explanation:

Given : Number of multiple choice questions = 2

Choices given in each question = 5

Since only one choice is correct out of 5.

So, the probability of selecting the correct answer = $\dfrac{1}{5}$

Also, both questions are independent of each other.

It means , The probability of answering the two multiple choice questions correctly if random guesses are made

=( Probability of selecting the correct answer in question 1 ) x ( Probability of selecting the correct answer in question 2 )

= $\dfrac{1}{5}\times\dfrac{1}{5}= 0.04$

Hence, the required probability =0.04
