Answer:
Step-by-step explanation:
The easiest way to get the answer is to<em> convert the decimal form into its fraction form. </em>All you have to do is to take note of the <em>number of decimal places</em> in order to raise the number into the power of ten. 0.3 has one decimal place, thus, you can use 10.
Since there's no common factor, there's no cancellation needed. So, the answer is .
Let' check.
If you divide 3 by 10, you will get the answer 0.3.
- 3 ÷ 10 = 0.3 (It's correct)
You can get equivalent fractions to this by multiplying or dividing the numerator by the same number.
Example: x
=
You may also use the fraction for your answer as this is also equivalent to 0.3.

Answer:
E(X)=3.125
Step-by-step explanation:
We are given that two four sided dice.
Then , the sample space
{(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(2,4),(3,1),(3,2),(3,3),(3,4),(4,1),(4,2),(4,3),(4,4)}
Total number of outcomes=16
Let the random variable X represent the maximum value of the two dice
Outcomes X P(X)
(1,1) 1 1/16
(1,2),(2,1),(2,2) 2 3/16
(1,3),(2,3),(3,1),(3,2),(3,3) 3 5/16
(1,4),(3,4) ,(2,4),(4,1),(4,2),(4,3),(4,4) 4 7/16
Using the probability formula
Now,
