<h3>
The probability of not choosing 2 peaches is
.</h3>
Step-by-step explanation:
Here, the total number of bins = 10
Total orange bins = 2
Total apples bins = 3
Total peaches bins = 4
Total melon bins = 1
Let E : Event of picking two peaches
So, P(Picking 1 peach ) = ![\frac{\textrm{Total peaches in bins}}{\textrm{Total bins}} = \frac{4}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BTotal%20peaches%20in%20bins%7D%7D%7B%5Ctextrm%7BTotal%20bins%7D%7D%20%20%20%3D%20%5Cfrac%7B4%7D%7B10%7D)
and P (Picking 2nd peach ) = ![\frac{\textrm{Total peaches in bins}}{\textrm{Total bins}} = \frac{3}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BTotal%20peaches%20in%20bins%7D%7D%7B%5Ctextrm%7BTotal%20bins%7D%7D%20%20%20%3D%20%5Cfrac%7B3%7D%7B9%7D)
![\implies P(E) = \frac{4}{10} \times\frac{3} {9} = \frac{2}{15}](https://tex.z-dn.net/?f=%5Cimplies%20P%28E%29%20%3D%20%5Cfrac%7B4%7D%7B10%7D%20%20%5Ctimes%5Cfrac%7B3%7D%20%7B9%7D%20%20%3D%20%5Cfrac%7B2%7D%7B15%7D)
So, the probability of not picking 2 peaches = 1 - P(picking 2 peaches)
![= 1 - (\frac{2}{15} ) = \frac{13}{15}](https://tex.z-dn.net/?f=%3D%201%20-%20%28%5Cfrac%7B2%7D%7B15%7D%20%29%20%3D%20%5Cfrac%7B13%7D%7B15%7D)
Hence, the probability of not choosing 2 peaches is

Answer:
42
Step-by-step explanation:
1
29
+13
42
Let the angles be 3x,3x and 4x
so 3x+3x+4x = 180
therefore x= 18
so, angles are 54,54,72 °
so it's B !!
Answer:
The number of faces is 29
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
![V- E + F = 2](https://tex.z-dn.net/?f=V-%20E%20%2B%20F%20%3D%202)
In this problem we have
![V=16](https://tex.z-dn.net/?f=V%3D16)
![E=43](https://tex.z-dn.net/?f=E%3D43)
Substitute in the formula and solve for F
![16- 43 + F = 2](https://tex.z-dn.net/?f=16-%2043%20%2B%20F%20%3D%202)
![-27 + F = 2](https://tex.z-dn.net/?f=-27%20%2B%20F%20%3D%202)
![F = 2+27](https://tex.z-dn.net/?f=%20F%20%3D%202%2B27)
![F = 29](https://tex.z-dn.net/?f=%20F%20%3D%2029)
Answer:
Step-by-step explanation:
equations are created to solve for a certain variable. you can use the data given in the word problem to formulate a valid equation that incorporates all important components of the word problem. the variable can be represented as any letter (most commonly x or y) to find a value that is inconsistent or unknown. this is helpful to find a certain thing in the problem, such as the amount of hours needed to earn a certain amount of money.
