If 21% of males and 15% of females in a given state play the guitar, what is the probability that a randomly selected subject in the state plays the guitar, given that the subject is male? 0.15 0.21 0.79 0.85

The probability that a randomly selected subject in the state plays the guitar is:

0.21

Step-by-step explanation:

Let 'x' be the number of male.

Now it is given that 21% of males play the guitar.

That means 21% of x play the guitar.

i.e. 21%×x play the guitar.

Hence, the probability that a randomly selected subject in the state plays the guitar, given that the subject is male is calculated as:

Probability=( number of male members playing the guitar)/(Total number of males)

Probability=

Hence, Probability is 0.21

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
