Write the expression 10 + 25 in a different way,

Harman [31]

25+10 is the answer

In the Commutative law of addition, it says that a+b and b+a are the same which makes ab and ba equal to one another.

To prove just add 10+25 and 25+10to show that both results in 35 (aka the same answer)

A multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered b

yaroslaw [1]

Answer:

Therefore, the probability is P=0.0084.

Step-by-step explanation:

We know that a multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered by guessing randomly.

Because we have 4 choices only one of which is correct, we get that p=0.25 and q=0.75.

We calculate the probability of getting exactly 6 correct answers.

n=9 and k=6.

$P=C_k^n\cdot p^k\cdot q^{n-k}\\\\P=C_6^9\cdot 0.25^6\cdot 0.75^3\\\\P=84\cdot 0.0001\\\\P=0.0084$

Therefore, the probability is P=0.0084.
