Question

Which statement illustrates a simulation that could be used to generate samples of people on a game show selecting either door A, door B, or door C?

Flipping a coin and getting heads for door A or tails for door C

O Rolling a die; 1 or 2 represents door A, 3 or 4 represents door B, and 5 or 6 represents door C.
O Creating a spinner divided into 4 equal parts. Label two parts door A, one part door B, and the third part door C.
O Go to the game show and collect data for a month on which doors people chose.​

Answer 1

Step-by-step explanation:

If coin A is selected then the number of times the coin would be tossed for a guaranteed Heads is 2, similarly, for coin B it is 3. Thus the number of times would be

Tosses = 2 * (1/4)[probability of selecting coin A] + 3*(3/4)[probability of selecting coin B]

= 2.75

Sir

Sub: Deteriorating standard of living in the capital city.

Through the columns of your reputed magazine, I wish to express my views on the deteriorating standard of living in the capital city of Delhi.

What does the standard of living actually mean? Does it mean possessing expensive goods of comfort and beauty, living in posh bungalows or, the overall decent and

peaceful living conditions including health and hygiene, pollution-free environment, and above all, a value-based society.

Considering all these, the living conditions in Delhi are really appalling. Dumps of garbage, heavy traffic congestion on the roads, growing atmospheric pollution, high levels of noise pollution, overcrowding at public places, etc., throw ample light on the deterioration in the people’s standard of living. Our lungs are hungry for fresh air and green belts.

The large number of immigrants, from other states to Delhi, put tremendous pressure on the resources of the city. The housing problem is growing rapidly with lack of civic amenities. The life is so busy that there is little interaction among neighbours. Hurry and worry is what best describes the life in the capital city. With growing consumerism and rising prices, the disparity between rich and poor is increasing day by day. Something judicious needs to be done to remedy this situation. More green belts and ‘silence zones’ should be created. The unrestricted inflow of people to Delhi should also be checked. Only then the standard of living can be improved.

Yours truly
