Answer: 0.444
Step-by-step explanation:
Given : Total burritos ordered = 15
Number of burritos with hot peppers =5
Number of burritos without hot peppers=10
Then the probability that the burrito has hot peppers:-
![\dfrac{5}{15}=\dfrac{1}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B15%7D%3D%5Cdfrac%7B1%7D%7B3%7D)
Using binomial probability formula:-
![P(X)=^nC_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%28X%29%3D%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
If you pick three burritos at random , then the probability of getting having exactly one burrito with hot peppers:-
![P(1)=^3C_1(\dfrac{1}{3})^1(\dfrac{2}{3})^{2}\\\\=(3)\dfrac{1}{3})^1(\dfrac{2}{3})^{2}=0.444444444444\approx 0.444](https://tex.z-dn.net/?f=P%281%29%3D%5E3C_1%28%5Cdfrac%7B1%7D%7B3%7D%29%5E1%28%5Cdfrac%7B2%7D%7B3%7D%29%5E%7B2%7D%5C%5C%5C%5C%3D%283%29%5Cdfrac%7B1%7D%7B3%7D%29%5E1%28%5Cdfrac%7B2%7D%7B3%7D%29%5E%7B2%7D%3D0.444444444444%5Capprox%090.444)
Hence, the required probability = 0.444
What if you divide it by 100?
