About 55% of the population of a large country is allergic to pollenallergic to pollen. if two people are randomly selected, what is the probability both are allergic to pollenallergic to pollen? what is the probability at least one is allergic to pollenallergic to pollen?

Both = 0.3025 or 30.25%

At least one = 0.7975 or 79.75%

Step-by-step explanation:

The probability that one of the two is allergic to pollen is 55% so the probability that both are allergic is given by:

The probability of at least one of them being allergic can be given by the whole minus the probability of neither being allergic:

4

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
