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
Step-by-step explanation:
A straight line is 180 degrees
Try to convert all of them, in one kind of unit, Here we will do for Kgs,
as we know, 1 kg = 1000 g
so, 2000g = 2 kg & 5050g = 5.050 Kg
Now, Arranging from smallest to greatest :
2 Kg < 3 Kg < 5.050 Kg < 75.75 Kg
In the end, you can re-replace the values, it would be:
2000 g < 3 Kg < 5050 g < 75.75 Kg
Hope this helps!
