Answer:
15
Step-by-step explanation:
a^2+b^2=c^2
y^2+8^2=17^2
Step 1: Simplify both sides of the equation.
y^2+64=289
Step 2: Subtract 64 from both sides.
y^2+64−64=289−64
y^2=225
Step 3: Take square root.
y=15
Probability of getting heads: 1/2
Probability to get 2 heads out of three tries is: 1/8
Work: 1/2 x 1/2 x 1/2 = 1/8
The events are independent. By definition, it means that knowledge about one event does not help you predict the second, and this is the case: even if you knew that you rolled an even number on the first cube, would you be more or less confident about rolling a six on the second? No.
An example in which two events about rolling cubes are dependent could be something like:
Event A: You roll the first cube
Event B: The second cube returns a higher number than the first one.
In this case, knowledge on event A does change you view on event B (and vice versa): if you know that you rolled a 6 on the first cube you don't want to bet on event B, while if you know that you rolled a 1 on the first cube, you're certain that event B will happen.
Conversely, if you know that event B has happened, you are more likely to think that the first cube rolled a small number, and vice versa.
Answer:
Tom started out with 57 games but sold 37 of them.
=> Now, Tom has: 57 - 37 =20 games
He put the rest in boxes with 5 games in each.
=> The number of boxes: 20/5 = 4 box
Hope this helps!
