Solve the equation.
512^x= 8
O {3}
O {1/3}
O {-1/3}
O {-3}

it's the 2nd one

Step-by-step explanation:

its 1/3

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
