The probability of a success and a failure is as follows,
P(success) = one - fourth
P(failure) = three - fourth
Definition of Probability
The area of mathematics that deals with numerical representations of the likelihood that an event will occur or that a statement is true is known as Probability. An event's probability is a number between 0 and 1, where, 0 generally denotes the event's impossibility and 1 denotes certainty of that event.
Calculating the Probability
The formula for finding the probability of an event to occur is given by,
P = (favorable outcomes)÷(total number of outcomes)
Now, it is given that each multiple choice question consists of 4 choices.
And, out of these four choices, only one answer is true.
Then, if Laila guesses the answer, the probability of choosing the right answer is given by,
P(success) =1/4
Thus, the probability of choosing the wrong answer will be,
p(failure) = 1 - P(success)
⇒ P(failure) = 1 - (1/4)
⇒ P(failure) = 3/4
