The event "not rolling 1, 3, 4, or 5" is the same event as "rolling 2 or 6".

Since the possible outcomes of a number cube have the same probability, the probability of rolling 2 or 6 is given by

$\dfrac{\text{\# of good outcomes}}{\text{\# of possible outcomes}}=\dfrac{2}{6}=\dfrac{1}{3}$

Answer:

84 pieces of fruit.

Step-by-step explanation:

I got this answer by doing 12*6 = 72, but this is not our final answer because we still have to add the pineapples which gives us 84.

Hope this helps!!

A horse race has 1313 entries and one person owns 44 of those horses. Assuming that there are no ties, what is the probability

777dan777 [17]

Answer: 0.0014

Step-by-step explanation:

Given : Number of entries in horse race = 13

Number of horses owned = 4

We assume that there are no ties .

Then , the probability that those four horses finish first, second ,third ,and fourth is given by :-

$\dfrac{4!}{^{13}P_4}=\dfrac{4!}{\dfrac{13!}{(13-4)!}}\\\\=\dfrac{4!\times9!}{13!}=.0013986013986\approx0.0014$

Hence, the required probability = 0.0014

Select the expression that has a value of 96.45

leonid [27]

Given:

Number is 96.45.

To find:

The expression that has a value of 96.45.

Solution:

In option a,

$0.9645\times 10^2=0.9645\times 100$

$0.9645\times 10^2=96.45$

In option b,

$9.645\div 10^1=\dfrac{9.645}{10}$

$9.645\div 10^1=0.9645\neq 96.45$

In option c,

$964.5\times 10^3=964.5\times 1000$

$964.5\times 10^3=964500\neq 96.45$

In option d,

$9645\div 10^3=\dfrac{9645}{1000}$

$9645\div 10^3=9.645\neq 96.45$

Therefore, the correct option is a.
