The probability that a randomly selected person at a show has seen the band play live before is 30%. A "superfan" is defined as someone who has seen the band play live at least 10 times. The probability that a person at a show is a "superfan" is 20%. Two people are selected at random. What is the probability that both people have both seen the band perform live before, and are superfans?

0.09 and 0.04

Step-by-step explanation:

The probability that a randomly-selected person at a show has seen the band play live before is 30%=0.30

The probability that a person at a show is a "superfan" is 20%=0.20

Two people are selected at random.

The probability that both people have both seen the band perform live before  = The probability that the first person has seen the band live before and the second person also has seen the band live before.

=0.30 x 0.30

=0.09

Similarly, the probability that both are  "superfans"   = The probability that the first person is a superfan and the probability that the second person is a superfan.

=0.20 x 0.20

=0.04

Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.09 and 0.04 respectively.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

5 x 14?

im new, sorry if this is wrong.
