It’s the Last one bcuz you have to divide y by the X and the last one all equal to 0.5

Answer:
It's either his house or they are the same distance
Step-by-step explanation:
I'm gonna say that they are the same distance from the library because his school is 10 blocks west of the library and his house is 10 blocks east.
Hope this helps!
Answer:
P(success)=0.2 matches the probability histogram.
Step-by-step explanation:
Formula : ![P(X)=^nC_r p^r(1-p)^{n-r}](https://tex.z-dn.net/?f=P%28X%29%3D%5EnC_r%20p%5Er%281-p%29%5E%7Bn-r%7D)
Where X represents the number of successes.
p represents probability of success .
1-p represents probability of failure.
Now when X= 0 the probability is 0.64 (Using histogram )
So, ![^2C_0 p^0(1-p)^{2}=0.64](https://tex.z-dn.net/?f=%5E2C_0%20p%5E0%281-p%29%5E%7B2%7D%3D0.64)
![(1-p)^{2}=0.64](https://tex.z-dn.net/?f=%281-p%29%5E%7B2%7D%3D0.64)
![(1-p)=\sqrt{0.64}](https://tex.z-dn.net/?f=%281-p%29%3D%5Csqrt%7B0.64%7D)
![(1-p)=0.8](https://tex.z-dn.net/?f=%281-p%29%3D0.8)
![1-0.8=p](https://tex.z-dn.net/?f=1-0.8%3Dp)
![0.2=p](https://tex.z-dn.net/?f=0.2%3Dp)
So, the probability of success = 0.2
Hence P(success)=0.2 matches the probability histogram.
