Answer:

ractions whose denominator is a power of 2 (¼, and 1/8) are terminating decimals. Even not on the table, we can also test fractions whose denominator is a power of 5 (1/5, 1/25, 1/125) and would easily see that they are terminating decimals.

Step-by-step explanation:

zzz [600]

If two events are independent, then

$Pr(A\cap B)=Pr(A)\cdot Pr(B)$ .

Use formulas for conditional probabilities:

$Pr(A|B)=\dfrac{Pr(A\cap B)}{Pr(B)},\\ \\ Pr(B|A)=\dfrac{Pr(A\cap B)}{Pr(A)}$ .

For independent events these formulas will be:

$Pr(A|B)=\dfrac{Pr(A\cap B)}{Pr(B)}=\dfrac{Pr(A)\cdot Pr(B)}{Pr(B)}=Pr(A),\\ \\ Pr(B|A)=\dfrac{Pr(A\cap B)}{Pr(A)}=\dfrac{Pr(A)\cdot Pr(B)}{Pr(A)}=Pr(B)$ .

Now in your case $Pr(A)=x,\ Pr(B)=y$ and $Pr(A|B)=x,\ Pr(B|A)=y, Pr(A\cap B)=x\cdot y$ .

This shows that the only correct choice is A.

A bag of ice pops contains 2 flavored raspberry, 5 flavored lemon, and 3 flavored lime. Find the probability of each event.

alexira [117]

Answer:

A) 2/10 or 20%

B) 3/10 or 30%

Step-by-step explanation:

There are 10 ice pops.

10 is going to be your denominator

Your numerator is going to be whatever amount of ice pops is.

After finding your fraction, divide the numerator by the denominator.

Lastly turn your decimal into a fraction.

2/10=0.2=20%

Hope I helped you.
