The probability of an event is notated P(event) in mathematics.
So if event A has a probability of 0.73, notationwise we say P(A)=0.73

Answer: Option '' a " is correct.

Step-by-step explanation:

Since we have given that

the probability of an event A occurring is 0.73

that means A is an event.

and the chances of getting an event A is written by P(A).

So, it becomes,

Probability of getting an event A is given by

$P(A)=0.73$

Hence, Option '' a " is correct.

I need help on my math please

Dovator [93]

In a 2-way frequency table, you take the row entry and divide it by its row total to get a decimal.
For your example:
It starts out like this:
sunny snowy
Male: 17 11
Female: 15 16

Add the rows up.
sunny snowy     total
Male: 17 11 28
Female: 15 16 31

Then divide the number the by the total:
sunny     snowy     total
Male: 17/28 11/28 28
Female: 15/31    16/31 31

Yours says to round to the 1000th place, so it ends up like:
sunny snowy
Male: .607 .393
Female: .484 .515

Hope that helps!!

There are 15 European cities that Kevin would eventually like to visit. On his next vacation, though, he only has time to visit

Answer:

32760 different schedules are possible.

Step-by-step explanation:

The order is important.

For example

Prague on Monday, Berlin on Tuesday, Liverpool on Wednesday and Athens on Thursday is a different schedule than Berlin on Monday, Prague on Tuesday, Liverpool on Wednesday and Athens on Thursday.

So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!)}$

How many different schedules are possible?

Choose 4 cities among a set of 15. So

$P_{(15,4)} = \frac{15!}{(15-4)!)} = 32760$

32760 different schedules are possible.

Answer:

86%

Step-by-step explanation:

Let g represent the mean mark for the 10 girls in the class. Then the mean mark for the class was ...

10g +20(62%) = 30(70%)

g = 3(.7) -2(.62) . . . . . . . . . divide by 10 and subtract 2(.62)

g = .86 = 86%

The mean mark for girls was 86%.

_____

You can do this in your head if you consider it in terms of deviations from the mean. The second equation above can be rewritten and factored as ...

g = 70% +2(70% -62%)

That is, because there are 2 boys for every girl, the girl's score is above the mean by an amount that is 2 times the amount that the boy's score is below the mean. The boys' score is below by 8%, so the girls' score is above by 16%, so is 86%.
