Answer:
0.7 = 70%.
Step-by-step explanation:
There are 5 cans, and she will pick 2, so the number of possibilities that she can pick 2 cans is a combination of 5 choose 2:
C(5,2) = 5!(3!*2!) = 5*4/2 = 10
To find how many possibilities there are with at least 1 can of soup, we can find the number of groups that include no cans of soup, and then see how many possibilities complete the total 10:
There are 3 "no-soup" cans, so the number of possibilities is a combination of 3 choose 2:
C(3,2) = 3!/2! = 3
So, there are 3 possibilities that have no cans of soup, so the number of possibilities that have at least 1 can of soup is 10 - 3 = 7
Then, the probability is 7 / 10 = 0.7 = 70%.
8/25....." / " simply means division
so 8 divided by 25 = 0.32
Answer:
1. 93/100
2. 8 21/100
3. 24/100= 6\50= 3/25
4. 57/100
5. 48/100 = 24/50= 12/25
6. 3 48/100= 3 12/25
7. 2.232323= 2232323/1000000
2 232323/1000000
Answer:
D
Step-by-step explanation:
x^2-10x=11
(x-5)^2=11+25
(x-5)^2=36
