Answer:
A. Because he doesn’t like to eat Chinese food too much in a short period of time, p is not really the same for each trial and so we cannot use the binomial distribution to calculate the desired probability.
Step-by-step explanation:
As it is mentioned in the question that he doesn't like the Chinese too much in a very short interval so he prefers various other foods for dinner
So now we have to determine the probability for the next 7 days
So based on the options mentioned, we prefer option A as we do not use the binomial distribution here as it shows only success results that are not confirmed in the given case
Therefore, the correct option is A.
Answer:
Step-by-step explanation:
The greatest common factor is 4r so
4r(d-4)
The second choice is best.
Show that c=x, so ΔABC ≅ ΔRTS and so ...
_____
The fact that a²+b²=c² is proof enough that ΔABC is a right triangle.
