Hello Jessnic.
What is considered passing? Getting all 4 questions correct? 3 correct?
What is the probability of answering onw correctly? There are 4 choices, so 1/4.
Now, suppose you answer the next one correct; you still have 1 in 4.
So, the probabiltiy of getting 2 in a row right is (1/4)(1/4). See? Now what's the
probabiltiy of getting all 4 correct?
