Suppose there is a 17.5 % probability that a randomly selected person aged 35 years or older is a smoker. In​ addition, there is a 25.5 % probability that a randomly selected person aged 35 years or older is female comma given that he or she smokes.

What is the probability that a randomly selected person aged 35 years or older is female and smokes?
Would it be unusual to randomly select a person aged 35 years or older who is female and smokes ?

a)  P(U and T) = 0.045

b) YES!, a randomly selected person aged 35 years and older is a female and smokes are an unusual.

Step-by-step explanation:

Let T represents the event that the randomly selected person is a smoker

Let U represents the event that the randomly selected person is female.

Given that; there is a 17.5% probability that a randomly selected person agef 35 years or older is a smoker.

i.e P(T) = 0.175

and there is a 25.5% probability that a randomly selected person aged 35 years or older is a female, given that he or she smokes.

i.e P (U|T) = 0.255

Then;

P (U|T) =

0.255 =

P(U and T) = 0,255 × 0.175

P(U and T) = 0.044625

P(U and T) = 0.045

∴ The probability that a randomly selected person aged 35 years or older is female and smokes is 0.045

b)

The probability that a randomly selected person aged 35 years or older is female and smokes is 0.045.

It is seen that the probability is less than 0.05; thus illustrating that the randomly selected person aged 35 years or older is female and smokes is an unusual event.

∴ YES!, a randomly selected person aged 35 years and older is a female and smokes are an unusual.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
