Answer:
the probability is 0.125
Step-by-step explanation:
The number of ways in which the mouse can move in the 4 turns is calculated using the rule of multiplication as:
<u> 2 </u>* <u> 2 </u> * <u> 2 </u>* <u> 2 </u> = 16
1st turn 2nd turn 3rd turn 4th turn
Because the mouse can take two options at every turn, right or left.
Now, from the 16 possibilities of movements, a mouse will find an exit in just two options:
1. right-right-left-left
2. left-right-right-left
So, the probability that a mouse will find an exit is:

Because, there are 16 possibilities and a mouse will find an exit using 2 of them.
Answer is a. You are trying to get x so that would be your answer “x=“ then you have Z and y left. This is still going to be a fraction since there is that line there still and won’t move. M is independent so that will be the denominator. You now have +y-z. This will then be on top and the reason why it’s on top is because most equations have the expression on top so it’s a numerator.
