Answer:
old town has 150 steps 
Step-by-step explanation:
Let the number of steps in the old tower be m
Mathematically, time = distance/speed
In this case, the distance is the number of steps while the speed is the rate of climbing or descending
For climbing, time spent = m/3
For descending time spent = m/2
Since it took her 25 longer when descending;
This means that;
m/2 - m/3 = 25
(3m-2m)/6 = 25
m/6 = 25
m = 6 * 25
m = 150 steps

Answer:
A. the number of possible out comes
Step-by-step explanation:
Probability is the chance of an event/something to happen.
The formula is;
Probability = the number of ways of achieving success/Total number of outcomes
The numerator position will have a value to show the number of ways of achieving success while the denominator will show the number of outcomes
For example the number of possible outcomes when a coin is flipped is 2, a tail or a head. So the probability of getting a head is P(H)= 1/2 where 2 is the number of outcomes
