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:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
