There are 5 numbers: 0,1,2,3,4.
m = 5, n = 3;
The probability of success:
P ( A ) = m / n = 3 / 5 = 0.6, or 60 %.
Answer: D) 60%
Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earths conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.
Since Jordan needs to use the high power objective in order to view the specimen under the light microscope. He should use the ocular lens in order to view the high power objective which is placed in the objective lenses. So he needs to use the ocular lens for viewing and the objective lens to magnify and see the specimen clearly on the stage.
