Answer:
A = choosing a red marble
B = choosing a green marble
Probability of A happening = P(A) = 5/(3+5+4) = 5/12
Probability of B happening = P(B) = 4/(3+5+4) = 4/12
Probability of either happening = P(A) + P(B) = 5/12 + 4/12 = 7/12
The key word in their question is red OR green and that is why we add the two probabilities. If they ask the probability of them both happening (if they said red AND green), you would multiply P(A)*P(B).

Answer:
(5/24) gallons of gas to mow the side yard
Step-by-step explanation:
We can easily solve this proble by applying a rule of three
5/16 gallons of gas --------------------------------- for 1 backyard
x gallons of gas ------------------------------------- 2/3 backyard
x = ((2/3)/1)*(5/16) gallons of gas
x = ((2/3))*(5/16) gallons of gas
x = ((10/48) gallons of gas
x = (5/24) gallons of gas
For the answer to the question above,
<span>the angle of 360 ° → π.d </span>
<span>the angle of x ° → 8π </span>
<span>You make the cross-multiply and you can get: </span>
<span>x * π.d = 8π * 360 </span>
<span>x * d = 8 * 360 </span>
<span>x = 8 * 360/d → where d = 2r </span>
<span>x = 8 * 360/2r </span>
<span>x = 4 * 360/r → where r = 4.5 cm </span>
<span>x = 4 * 360/4.5 </span>
<span>x = 320 °</span>
