Answer:

Fraction =  13/20

Decimal =  0.65

Percent = 65%

Step-by-step explanation:

<em><u>Given:</u></em>

13 out of 20 emails in mail inbox are junk emails

<em><u>Solve for:</u></em>

The experimental probability that next email is junk

<em><u>Solution:</u></em>

Step 1: Define the formula for calculating the probability

P = number of elements/total number of elements

Step 2: Perform the calculation

The number of elements (junk emails) = 13

The total number of elements (all emails) = 20

=> P(obtain odd number in experiment) in fraction form = 13/20

=> P(obtain odd number in experiment) in decimal from = 0.65

=> P(obtain odd number in experiment) in percent form = 0.65 x 100 = 65%

Hope this helps!

:)

Statistics show that about 42% of Americans voted in the previous national election. If three Americans are randomly selected, w
MrRa [10]

Answer:

19.51% probability that none of them voted in the last election

Step-by-step explanation:

For each American, there are only two possible outcomes. Either they voted in the previous national election, or they did not. The probability of an American voting in the previous election is independent of other Americans. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

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

And p is the probability of X happening.

42% of Americans voted in the previous national election.

This means that p = 0.42

Three Americans are randomly selected

This means that n = 3

What is the probability that none of them voted in the last election

This is P(X = 0).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{3,0}.(0.42)^{0}.(0.58)^{3} = 0.1951

19.51% probability that none of them voted in the last election

a submarine travels at an elevation of -75 3/4 ft relative to sea level then its elevation changes by - 16 3/8 what is the new e
slamgirl [31]

Answer:

New = -92\frac{1}{8}

Step-by-step explanation:

Given:

x = -75\frac{3}{4} --- Position

\triangle x = -16\frac{3}{8} --- Change

Required

Find the new position

The new position is calculated as:

New = x + \triangle x

New = -75\frac{3}{4} - 16\frac{3}{8}

New = -75.75 - 16.375

New = -92.125

New = -92\frac{125}{1000}

New = -92\frac{1}{8}
