5. A group of people were asked if they believed in space creatures. 182 responded "Yes" and 220 responded No" Find the probabil
svet-max [94.6K]

Answer:

\frac{110}{201}, 0.55, 55%

Explanation:

So first you have to find the total number of people.

182 + 220 = 402

Then we put that number in a fraction with the number of people who do not believe in the creatures.

\frac{220}{402}\\55

Then we simplify it.

\frac{220}{402}=\frac{110}{201}\\

That is our fraction answer. In order to change it into a percent we divide the numerator by the denominator.

\frac{110}{201}=0.54726368159\\

Then we round to the nearest hundredth (or what ever it says).

0.55

And that is our decimal. Now to change that into a percent we multiply by 100, or move the decimal to spaces to the right.

55%

And that is our percent.

The weather forecaster says that the probability of rain on Saturday is 20% and the probability of rain on Sunday is 30%. a. Can
Annette [7]

Answer:

0.44

Step-by-step explanation:

given that the weather forecaster says that the probability of rain on Saturday is 20% and the probability of rain on Sunday is 30%.

It is common sense to know that Saturday and Sunday are independent of the other

Hence Probability that it rains on both days = 0.2*0.3=0.06

Since for independent events joint probability is the product of probabilities

required probability

= probability of rain over the weekend (Saturday or Sunday

= P(Sunday)+P(Saturday) -P(both)

=0.2+0.3-0.06\\=0.44

Mitch lives on the 20th floor of an apartment building. Every time he leaves, he rides a self-service elevator from the 20th flo
weeeeeb [17]

Answer:

He does that because he is short and his hand can't reach the 20th floor button

Step-by-step explanation:

Mitch does that simply because he is short.

When he is leaving, he doesn't need to reach the 20th floor button because the button is way taller than the reach of his hands whereas when he is returning he has to reach the 20th floor button but his hand can only reach the 15th floor button. Thus, he gets to the 15th floor and walks up the remaining 5 flights.
