May Fly..
An insect. Its life span is just a day.
Some insects.
The answer will depend on the underlying distribution, which is not specified. The normal distribution, although often used at school is not really appropriate because it allocates a positive probability to the event that the lifespan is negative. That is clearly an impossible event! A more appropriate distribution is often the lognormal.Anyway, assuming that you are of school age, and therefore assuming a normal distribution,P(Lifespan < 136) = 0.37P(Lifespan > 150) = 0.20
Less than one year
less than three years
The life span of the Weaver bird is currently unknown to modern science, no studies have been done to pinpoint it. Interestingly, we (as a collective species) know the lifespan of less animals than ones we don't know the lifespan of.
There are not many insects that live less than a few days. One insect that has a lifespan of 24 hours is the Mayfly.
the average lifespan of the white footed mouse is usually less than two years.
They are aquatic species and they have more organs than us humans.
Febuary has less than 30 days.
Treadmills are generally considered non-durable consumer goods. This means that their expected lifespan is less than 3 years. However, it will greatly depend on how they are treated and maintained. Less than 2 weeks is not usual and should be returned.
365 - 366 days. It depends on the species. Some live less than a year, while others live for decades.
They have the most species.
