Answer:
1/12
Step-by-step explanation:
P(4) = number of 4's/ total
There is one 4 on dice and there are 6 different numbers
P(4) = 1/6
P(tail) = number of tails/ total
There are 2 sides on a coin and only one is a tail
P(tail) = 1/2
P(4 and a tail) = P(4)*(Ptail) since they are independent events
= 1/6*1/2
= 1/12
= 1/2×1/6=1/12.
There is a one in 6 chance that you will roll a 4 and a one in 2 chance that you will flip heads .

Answer:
{13.7, 13,7/100 –13,17/100 –13.2}
Step-by-step explanation:
She must have multiplied it by 5.
That would've given her:
x - y = 15
2.5x + y = 25
Now we can add them and the y-terms will eliminate each other. Because one is -y, and the other is positive y. -y + y = 0.
let g(x) = x^2+2
let f(x) = 9/x
f(g(x)) is therefore equal to f(x^2 + 2) which is equal to 9/(x^2+2).
