The number of years a Mars rover is expected to function on the surface of Mars is exponentially distributed with parameter λ = 0.25. If the company Budget Mars Explorer Inc. successfully lands a Mars rover on the planet Mars, what is the probability that it will be working for an additional 10 years after it last sent a communication to mission control?

the probability that it will be working for an additional 10 years after it last sent a communication to mission control is 0.0821

Step-by-step explanation:

Given that;

years a Mars rover is expected to function on the surface of Mars λ = 0.25

probability that it will be working for an additional 10 years after it last sent a communication to mission control?

Now x is number of years a Mars rover function

f(x) = 0.25e^-0.25x , 0 < n < ∞

so

P( X>10 ) = ₁₀∫^∞ 0.25e^(-0.25n) dn

= e^(-0.25 × 10)

= e^(-2.5})

= 0.0821

therefore the probability that it will be working for an additional 10 years after it last sent a communication to mission control is 0.0821

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
