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:
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
Answer:
59
Step-by-step explanation:
pls don't take my word as a final answer pls if u can do some more research
The answer to this question is -3/35
So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
a/b and c/d are rational numbers with a,b,c,d intergers
so with the same denominators ( equaling a+c over b) or different ones (equaling ab+cb over bd) they end up with the answers of
same denominator= b is not equal to 0
different denominators= d is not equal to 0
this may not make sense but i'm pretty sure i understood you right
