Answer:
False
Step-by-step explanation:
To be a function each x can only go to one y
The number 5 goes to both 2 and 1, which violates the rule
Therefore, this is a relation, not a function
Answer:

And using the probability mass function we can find the individual probabilities:


And replacing we got:
![P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%202%29%3D1%20-%5B0.2044%20%2B0.3590%5D%3D%200.4366)
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
Step-by-step explanation:
Let X the random variable of interest "number of seniors who disapprove of daily smoking ", on this case we now that:

The probability mass function for the Binomial distribution is given as:

Where (nCx) means combinatory and it's given by this formula:

And we want to find this probability:

And using the probability mass function we can find the individual probabilities:


And replacing we got:
![P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%202%29%3D1%20-%5B0.2044%20%2B0.3590%5D%3D%200.4366)
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
Answer: 10 times
Step-by-step explanation:
1 litre = 1000 ml
6 litres = 6000 ml
Lawnmover holds 600 ml
So 6000 ml will fill
6000/600 = 10 times
