Answer: i think is C
Step-by-step explanation: Experimental probability is the probability of what actually happens in the given experiment.
We know that a fair six-sided cube is rolled 60 times and the outcome 2 has occurred 15 times out of 60 times.
Therefore, the experiment probability in the given experiment is:
Experimental probability of rolling 2
Now, the theoretical probability is the probability of what is expected from the random experiment. We know that a cube has 6 sides and the theoretical probability of getting 2 is given below:
Theoretical probability of rolling a 2
Therefore, the correct option is:
The experimental probability of rolling a 2 is and the theoretical probability of rolling a 2 is .
<span>25/28 is the probability of picking two or three white balls.
Given that there are only 8 balls in total and of those 8, 5 of them are blue, this problem can be turned around to "What's the probability of selecting 5 blue balls?" And then subtracting that result from 1.
There are a total of 6 ways of selecting all 5 blue balls. The only difference is when the single white ball is selected. The 6 ways are BBBBBW, BBBBWB, ..., WBBBBB. So let's calculate the probability of each of those 6.
5/8 * 4/7 * 3/6 * 2/5 * 1/4 * 3/3 +
5/8 * 4/7 * 3/6 * 2/5 * 3/4 * 1/3 +
5/8 * 4/7 * 3/6 * 3/5 * 2/4 * 1/3 +
5/8 * 4/7 * 3/6 * 3/5 * 2/4 * 1/3 +
5/8 * 3/7 * 4/6 * 3/5 * 2/4 * 1/3 +
3/8 * 5/7 * 4/6 * 3/5 * 2/4 * 1/3 = ?
If you look closely at each of the 6 lines, you'll realize that the numerator will always be the product of 5!3 and the denominator will be 3*4*5*6*7*8. So, let's simplify to
6*5!3/(3*4*5*6*7*8)
= 6*5*4*3*2*3/(3*4*5*6*7*8)
= 2*3/(7*8)
= 3/(7*4)
= 3/28
Now we just need to calculate 1 - 3/28 = 28/28 - 3/28 = 25/28</span>
2 in: 8 ft simplifies to 1 in: 4 ft which is just generally easier to work with.
1 in: 4 ft = 3 in: x ft
x ft= 4*3 = 12
The length of the actual room is 12 feet.
Hope this helps!
Answer:
It would be 90
Step-by-step explanation:
If you look at it you can see it is a right angle. And a right angle is always 90 degrees. Hopes this helps and have a nice day and stay safe
Start by taking away 22.36 from each side so that you are left with 4.73c = 42.57
And then divide each side by 4.73 so you will get c = 9
