Answer: 15/91 which is choice B
=================================================================
There are two methods to find this answer.
Method 1) We have 6 girls and 8+6 = 14 students. The probability of picking a girl is 6/14 = 3/7. After the first girl is chosen, we have 5 girls left out of 14-1 = 13 students overall. The probability of picking another girl (assuming the first selection was a girl) is 5/13. Multiply these probabilities: (3/7)*(5/13) = (3*5)/(7*13) = 15/91
--------------------
Method 2) We can use the nCr combination formula. Order does not matter.
We have nCr = 6 C 2 = 15 ways to pick 2 girls. See the attached image below for the steps (figure 1)
Out of nCr = 14 C 2 = 91 ways to pick 2 students. See the attached image below for the steps (figure 2)
So that's another way to get the answer 15/91.
Answer:
7
Step-by-step explanation:
20 • 35% = 13 20-13=7
Answer:
Always
Step-by-step explanation:
A mononomial's variable can only have exponents 0,1,2,3 etc so the product will also be a mononomial.
The triangles are similar because two angles have the same measurements
Answer: 4x+y=567, x+y=279, where x=96 and y=183. X represents the large bags and y the small bags
Explanation: We know that our two totals are 279 and 567, so they will be on their own sides of the equation.
The number of large bags (x) plus the number of small bags (y) equals 279 bags in total.
As it relates to price, the price of the large bags (4x) plus the price of the small (y) gives us $567.
