Hey!!
the answer is 0.02 !.
if helped, brainliest
They are the same because if you add a zero it doesnt change it
Answer:
a. 
b. 0.7
c. 0.7=70%=
Step-by-step explanation:
70% of 100 received an A, that is 70/100 times 100 equal to 70

a. 70% = 
b.
= 0.7
Notice that 70/100 is equal to 7/10 which is 0.7
c. 0.7=70%=
We can solve this problem using the binomial distribution. A binomial distribution<span> can be thought of as a success or failure outcome in an experiment or survey that is repeated multiple times.
</span>Probability function of binomial distribution has the following form:

p represents the probability of each choice we want. k is the number of choices we want and n is the total number of choices.
In our case p=0.85, k=5 and n=6.
We can now calculate the answer:

The probability is 39%.

Just do 3^2 * 3^2 he is incorrect because he multiplied the exponents and he was suppose to add them together. the correct answer should be 3 to the 4th power which is 81
