Given:
Rolling a fair dice.
To find:
The theoretical probability of rolling a number less than 5.
Solution:
The possible numbers of rolling a dice are 1, 2, 3, 4, 5, 6.
Total outcomes = 6
Numbers less than 5 are 1, 2, 3, 4.
Favorable outcomes = 4
Now, the theoretical probability of rolling a number less than 5 is:



In decimal form, it can be written as:

In percentage form, it can be written as:


Therefore, the theoretical probability of rolling a number less than 5 in the fraction, decimal and percent are
and
respectively.

Answer:
56
Step-by-step explanation:
probabilty of both being red= 0.5*0.6
total no of times spinners were spun = 84/(0.5*0.6) = 280
probabilty of both being blue= 0.5*0.4
Estimate = 0.5*0.4*280= 56
To solve for x and y, you need to know if the triangles are congruent. They are because of their congruent sides and exterior angles are the same measure.
Now you know that the triangles are congruent, you can set up a proportion for the side lengths you are looking for.
For x...
22/10=x/12. Then cross mutiply. x =26.4
You can do this because the triangles are congruent.
For y...
22/10 =37.4/y. Then you cross multiply. y=17
The correct answer is B.
