Four teams (1, 2, 3 and 4) have qualified for the final of the cricket world cup. Team 1 plays Team 2.
Team 3 plays Team 4. The winners then play in the final. In a game between Team “i” and Team “j”,
the probability of team “i” winning is given by {i /(i+j)}. Then what is the conditional probability that
“Team 1” will win the World Cup? (Note: Enter your **answer in decimals** rounded to two decimal

Question 221 MCQ · 1.0 marks
A cosmetics brand “SwamiIsBeautiful” manufactures three products, “Face Creams (FC)”, “Body
Lotion (BL)” and “Lip Gloze (LG)”. The company believes displaying all their products together in a
single shelf at a retailer store will help boost their sales, as people tend to pick up the items
together. Hence, they are currently spending a lot of money to make sure that the retailers display
the products together.
However, on hearing this, Dr.Milo feels sceptical as it is counter intuitive. He feels that the sales of
the products are independent. To check his theory, data in Table-3 was collected. Table-3 contains
the total sales (in quantity) of the three products across retail stores. Here, the retail stores were
classified in two types: “Type-1: The three products are displayed together”, “Type-2: The three
products are not displayed together”. Given this information answer the given subquestions.
(Note: For all questions in this comprehension, if your answer is in decimal, enter it rounded to two
decimal places. For example, if your answer is “10.256”, enter it as “10.26”)
