The probability is still calculated the same way, using the number of possible ways to outcome can occur divided by the total number of outcomes.

I just took the test
Hello!
This is a problem about probability.
What we would first do is find the theoretical probability that Susan would roll the number 3 on a die.
Assuming that this is a fair six sided die, there is only one face with the number 3, and there are 6 sides, meaning that the probability that Susan rolls a 3 would be
.
Now, Susan is rolling a die 1,086, meaning that we can divide this number by 6 to find the theoretical number of times that Susan would roll the number 3 on this die.
You should get 181 times, which would be a good estimate of how many times she could roll the number 3.
Hope this helps!
Answer:
x = √30
Step-by-step explanation:
From small triangle BDC:
using Pythagorean theorem
CB² = BD² + DC²
x² = BD² + 3²
Fron triangles BDC and ADB.
ΔBDC has long leg BD and short leg DC.
ΔADB has long leg AD and shirt leg BD.
AD : BD = BD : DC
7 : BD = BD : 3
7*3 = BD*BD
BD² = 7*3 = 21
x² = BD² + 3² = 21+9 = 30
x² = 30
x = √30
