Answer:
The probability that the student will not guess correctly on any one question is 4/5
Step-by-step explanation:
The question posed is an application of the binomial probability distribution.
We have been informed that the test has multiple choice questions with 5 choices for each answer that only one answer is correct for each question.
If the student guesses the answer to each question, then the probability that the student will guess correctly on any one question is 1/5.
Therefore, the probability that the student will not guess correctly on any one question is;
1 - 1/5 = 4/5
Answer:
6/35
Step-by-step explanation:
After the first month, there are 4/7 remaining claims left to be paid. (1 -3/7 = 4/7)
In the second month, 2/5 of this 4/7 are paid. So we just need to work out

Answer: 220 cm squared
Step-by-step explanation: Formula for surface area of a prism...
S = 2(lw + lh + wh) l = 5 w = 10 h = 4
so
lw is 5 x 10 = 50
lh is 5 x 4 = 20
wh is 10 x 4 = 40
plug these into equation...
S = 2(50 + 20 + 40)
S = 2(110)
S = 220
