Answer:
The probability that the number of peas is at most 8 is 2.864
Step-by-step explanation:
The probability of any child having a green pod is 1\4=0.25
To have 12 peas with no pods it will have to occur 12 times.
So, we will raise it ti the 12th power,
Pno(green)= ![\frac{{1}{4}}^12](https://tex.z-dn.net/?f=%5Cfrac%7B%7B1%7D%7B4%7D%7D%5E12)
= 5.96
Therefore, for at most 8 green pod
=
2.864
ANSWER: -2y-10
Step-by-step explanation:
Answer:
let the numbers be
X , y and z
X+ y + z = 20
first number is 4 times the sum of other 2
X = 4(y+ z)
second is 7 times third
y = 7z
now substituting back
X= 4 (7z + z)
X= 32z
32z + 7z + z = 20
40z = 20
z = 1/2
y = 1/2 * 7 = 7/2
X = 1/2 * 32 = 32/2
1/2 * 7/2 * 16 = 28
28 is the answer!
