Step-by-step explanation:
Let A be the event of getting a factor of 15 when a fair spinner numbered 1 - 5 spins and B be the event that a fair coin is tossed.
The factors of 15 =
Then ,the probability of obtaining a factor of 15 is given by :-
The probability of getting a tail :-
Since both the events are independent , thus
The probability of obtaining a factor of 15 and a tail is given by :-
Hence, the required probability :
You can indeed use similar triangles to get a side of another similar triangle.

Answer:
11.
Step-by-step explanation:
We are asked to evaluate the expression , when y=6 and z=3.
To evaluate our expression at given values we will just substitute y=6 and z=3 in our given expression.
According order of operations (PEMDAS) we will multiply or divide our expression from left to right.
Therefore, the value of our given expression at y=6 and z=3 is 11.
