Answer:
the Earth is tilted on its axis
the Earth is a sphere
different materials on Earth's surface absorb heat at different rates
Explanation:
The heating and cooling rates of land and water differ. This effects the heating of the earth according to these substances. Since the planet Earth is spherical in shape, the equator heats up more as compared to that of the polar regions. The differences in the seasons is because of the axis on which the Earth is tilted. Because of rotation, the heating and cooling of the Earth's surface differ. These are the reasons that are the reason for the uneven heating of the sun.
Using the binomial distribution, it is found that there is a:
- 0.0036 = 0.36% probability that both are allergic to pollen.
- 0.1164 = 11.64% probability that at least one is allergic to pollen.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Researching the problem on the internet, it is found that:
- 6% of the population is allergic to pollen, hence p = 0.06.
- Two people are chosen at random, hence n = 2.
The probability that both are allergic is P(X = 2), hence:
P(X = 2) = 0.06^2 = 0.0036.
0.0036 = 0.36% probability that both are allergic to pollen.
The probability of at least one is:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.94^2 = 1 - 0.8836 = 0.1164.
0.1164 = 11.64% probability that at least one is allergic to pollen.
