Answer:
Line a. You can see at x=1 y=7.
Answer:
0.0000643
Step-by-step explanation:
The exponent is -5, making it 10 to the power of negative 5. When an exponent is negative, the solution is a number less than the origin or base number. To find our answer, we move the decimal to the left 5 times: 6.43 -> 0.0000643
Answer: 0.27648
Step-by-step explanation:
Given : The proportion of all individuals have group A blood : p=0.040
Total individuals give blood : n= 6
Let X be the number of individuals have group A blood.
Since all individual are independent of each other.
![X\sim Bin(n=6, p=0.40)](https://tex.z-dn.net/?f=X%5Csim%20Bin%28n%3D6%2C%20p%3D0.40%29)
Formula :
, where n= sample size , p = probability of getting success in each trial.
The probability that exactly three of the individuals have group A blood. :
![P(x=3)= ^6C_3(0.40)^3(1-0.4)^3\\\\= \dfrac{6!}{3!3!}\times(0.40)^3(0.60)^3\\\\=0.27648](https://tex.z-dn.net/?f=P%28x%3D3%29%3D%20%5E6C_3%280.40%29%5E3%281-0.4%29%5E3%5C%5C%5C%5C%3D%20%5Cdfrac%7B6%21%7D%7B3%213%21%7D%5Ctimes%280.40%29%5E3%280.60%29%5E3%5C%5C%5C%5C%3D0.27648)
The probability that exactly three of the individuals have group A blood. is 0.27648
