This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture. Thus, option (D) is correct.
Event - 1: Choosing a letter from the alphabet that is Q.
Let us assume the probability of happening of event 1 is P(Q).
Event - 2: Choosing a digit from 0-9 that is 7.
Let us assume the probability of happening of event 1 is P(7).
Now, we need to choosing the secret code that is 7Q.
We need to multiply both events to get the desired result.
Thus,
This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture.

Answer:
Option 4: P(7∩Q) = P(7) × P(Q)
Step-by-step explanation:
P(7∩Q) represents the probability of choosing the secret code "7Q".
If A and B are independent events, then,
P(A∩B) = P(A) × P(B)
Let A be the event of choosing a number from 0-9 and
B be the event of choosing an alphabet.
Clearly, A and B are independent.
Therefore,
P(7∩Q) = P(7) × P(Q)

Answer: The required time needed to deliver 72 papers is 2 hours 24 minutes.
Step-by-step explanation: Given that 9 papers are delivered in 18 minutes.
We are to determine the time needed to deliver 72 papers.
We will be using the UNITARY method to solve the problem.
We have
Time needed to deliver 9 papers = 18 minutes.
So, time needed to deliver 1 minute will be
Therefore, time needed to deliver 72 papers is given by
Thus, the required time needed to deliver 72 papers is 2 hours 24 minutes.
