Two dice are rolled. What is the probability that the sum of the numbers is exactly 10? What is the probability that the sum of the numbers is at least 10? What is the probability that the sum of the numbers is exactly 10, given that it is at least 10?
1 answer:
Answer:
exactly 10: 8.33 %
at least 10: 16.66 %
Step-by-step explanation:
first we have to see the amount of favorable results
4+6 = 10
6+4 =10
5+5=10
then we have to see the amount of possible results
Each dice has 6 faces and there are 2 dice, so if we make 6 ^ 2 we will get the number of possible combinations
6^2 =
6*6 = 36
Now we only do the number of favorable results on the possible results and multiply it by 100 and obtain the probability
100*3/36 = 8.33 %
we do the same for those greater than or equal to 10
4+6 = 10
6+4 = 10
5+5 = 10
6+5 = 11
5+6 = 11
6+6 = 12
100*6/36 = 16.66 %

2rd one I could be wrong tho
A. 62. If you add up all of the numbers, you get 310, then take this number and divide it by 5. you divide it by five because there are five numbers given.
First you multiply 3 x 1000 which is 3,000. Then you too 2 x 100 which is 200. Lastly you subtract 3000 from 200 and you get 2800.
Divide the top number by the bottom number
Answer:
=376.8
Step-by-step explanation:
V=n Where V is the volume , r is the radius and h is the perpendicular height .
r = m=6
h = 10m
n=3.14
v= 3.14 * 6*6 *
=376.8
