8 per package.
64*2= 128
Now we need to divide 128 by 8 to see how many packages we will need.
128/8= 16
Now we know that we need 16 packages so that we can feed 64 people 2 dinner rolls.
Final answer: 16 packages
Answer:D the last one
Step-by-step explanation:
Answer:
you want 4 correct and 16 incorrect
there are 20 questions
each question has four answers, so
P(right answer) = 1/4
P(wrong answer) = 3/4
----
Since you want 4 correct of 20 we have a combination of 20C4
This is a binomial problem where p = 1/4, q = 3/4 and we get
(20 "choose" 4)*(probability correct)^(number correct)*(probability incorrect)^(number incorrect)
putting numbers in we get
(20c4)*(1/4)^4*(3/4)^16
This gives us
~ .189685
