Fifteen children voted for their favorite color. The votes for red and blue together were double the votes for green and yellow
ratelena [41]
We know that there are 15 children altogether 

We know that the number that voted for B+R is double the number of students voted for G+Y

B+R = 2(G+Y)

Think of two numbers that add up to 15, one number is twice of the other number. 

For example, 6 and 12.
12 is double of 6 but 6 + 12 doesn't give 15

So, think again

for example 5 and 10
10 is double of 5 and 5+10 does give 15

So, the number that voted Red and Blue is 10 and the number that voted Yellow and Green is 5

A survey of athletes at a high school is conducted, and the following facts are discovered: 13% of the athletes are football pla
nekit [7.7K]

Answer:

The probability that an athlete chosen is either a football player or a basketball player is 56%.

Step-by-step explanation:

Let the athletes which are Football player be 'A'

Let the athletes which are Basket ball player be 'B'

Given:

Football players (A) = 13%

Basketball players (B) = 52%

Both football and basket ball players = 9%

We need to find probability that an athlete chosen is either a football player or a basketball player.

Solution:

The probability that athlete is a football player = P(A)= \frac{13}{100}=0.13

The probability that athlete is a basketball player = P(B)= \frac{52}{100}=0.52

The probability that athlete is both basket ball player and  football player = P(A\cap B) = \frac{9}{100}=0.09

We have to find the probability that an athlete chosen is either a football player or a basketball player P(A\cup B).

Now we know that;

P(A\cup B)= P(A) + P(B) - P(A \cap B)\\\\P(A\cup B) = 0.13+0.52-0.09=0.56\\\\P(A\cup B) = \frac{0.56}{100}=56\%

Hence The probability that an athlete chosen is either a football player or a basketball player is 56%.
