Seventy cards are numbered 1 through 70 , one number per card. One card is randomly selected from the deck. What is the probabil

Vanyuwa [196]

Answer:

$Probability = \frac{2}{35}$

Step-by-step explanation:

Given

$Total = 70$

First, we need to list the multiples of 5

$M_5 = \{5,10,15,20,25,30,35,40,45,50,55,60,65,70\}$

Then, multiples of 3 $M_3 = \{3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69\}$

Next, is to list out the common elements in both

$M_3\ n\ M_5 = \{15,30,45,60\}$

$n(M_3\ n\ M_5) = 4$

The required probability is then calculated as thus:

$Probability = \frac{n(M_3\ n\ M_5)}{Total}$

$Probability = \frac{4}{70}$

$Probability = \frac{2}{35}$

60 students on field trip 20 students were 8th graders. What ratio shows relationship between eighth graders and everyone who we

Flauer [41]

Answer:

Percentage=33.33%

Step-by-step explanation:

Total number of students=Number of 8th grader+others who went on trip

where;

Total number of students=60

Number of 8th graders=20

Others who went on trip=x

replacing;

60=20+x

x=(60-20)

x=40

Others who went on trip=x=40

Ratio of number of eighth graders to the number of everyone who went on the trip is;

Eighth graders who went=20 students

Everyone who went including the eighth graders=60

20/60==1/3

(1/3)×100=33.33%

Percentage=33.33%
