suppose you have a 1/10 chance of winning with a scratch off lottery ticket if you buy 5 tickets what is the probability of winning with all five

Answers

Answer 1

Answer:

What is probability ?

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Let us assume that, A be the event of winning the lottery.

The probability of winning is,

P(A) = 1/10

Since, 5 tickets are bought,

The probability of winning all five can be given by formula $^nc_rp^r.q^(n-r)$

According to the given condition,

n=5 and r=5

Probability = $^5C_5(1/10)^5$ = (1/10)⁵

Therefore, the probability of winning all five = (1/10)⁵

Answer 2

Answer:

Answer:

$10^(-5)$

Step-by-step explanation:

Let us assume that, A be the event of winning the lottery.

The probability of winning is,

$P(A)=(1)/(10)$

You bought 5 tickets. Winning all the five lotteries will be,

$P(\text{A and }\text{A and }\text{A and }\text{A and }\text{A})=P(A)\cdot P(A)\cdot P(A)\cdot P(A)\cdot P(A)\n\n=(1)/(10)\cdot (1)/(10)\cdot(1)/(10)\cdot(1)/(10)\cdot(1)/(10)=(1)/(10^(5))=10^(-5)$

2. The Salton Sink in California is approximately 215 feet below sea level. Which of the following best describes the location of the Salton Sink as it relates to sea level?

a –215
b 0
c +215
d +2150

Answers

We need to find the best way to represent the numbers.

The score will be best represented by $+4$

The depth of the Salton Sink will be best described as $-215$ .

$4$ under par means that it took $4$ less strokes than the par of the course to complete the course.

This represented by $-4$

The negative sign comes first.

If the score is $4$ over par then it took $4$ more strikes than the par of the course.

This score will be best represented by $+4$

Let, us take the surface sea level as $0$ .

So, the depth below the sea level will be negative and above it will be positive.

Hence, the depth of the Salton Sink will be best described as $-215$ .

Answers

Answer:

The answer is B. $x^2-9$

Step-by-step explanation:

This problem represents a "the Sum and Difference of the same two terms".

If you encounter the same two terms and just the sign between them changes, rest assured that the result is the square of those two terms. Also, the second term will always be negative.

For example:

$(a-b)*(a+b)=a^2-b^2$

So, in this case:

$(x+3)*(x-3)\nx^2-3*x+3*x-9\nx^2-9$

Therefore, the answer is B. $x^2-9$

B would be correct the -3 x and 3 x cancel out

What is 12 divided by 6/7

Answers

What is the easiest way to divide whole numbers to fractions?
Just follow these two easy steps:
1. Multiply the whole number to the denominator of the fraction. In other words, the bottom number of the fraction will be multiplied to the whole number, like this:

12 ÷ 6/7 = n
6
7 x 12
You will have 6/ 84.
2. Simplify.
6 = 1, 2, 3, 6
84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 42, 84

the GCF is 6. divide both numbers by 6, so the answer will be 1/14.

You can also get the reciprocal and proceed to multiplication , like this: (12/1 is the fractional form or the whole number 12.)
1/12 x 6/7=n
that makes 6/84 or 1/14.

12 / (6/7) = x
x = 12 * 7/6
x = 14
