Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have
ways to to choose 4 good components from 8.
We have
ways to choose 4 components from a total of 9.
If all function properly then none is bad, we
way to do this.
P(At least one)=![1-\frac{^8C_4*^1C_0}{^9C_4}](https://tex.z-dn.net/?f=1-%5Cfrac%7B%5E8C_4%2A%5E1C_0%7D%7B%5E9C_4%7D)
P(At least one)=![1-\frac{70*1}{126}](https://tex.z-dn.net/?f=1-%5Cfrac%7B70%2A1%7D%7B126%7D)
P(At least one)=0.4444
11/29 i believe. Cuz you add them all together and get 29 and then red and green added together is 11
Answer:
150
Step-by-step explanation:
100% represents 500 jars
Subtract the sum of the percentage of other jars for percent of blue jars
100 - (30 + 25 + 15) = 100 - 70 = 30%
That is 30% of the jars are blue
Calculate 30% of 500 to obtain number of blue jars
30% =
= 0.3, hence
number of blue jars = 0. 3 × 500 = 150
43
if so, use the formula for sum of interior angles in a polygon to solve. 7380 = (n - 2)(180), where n is the number of sides. The number of sides of the polygon is 43.
Use the volume formula for cylinder V=3.14r^2h then plug in all the info so its would be volume= 3.14*5^2*4
