5/7 of the 63 students in gym class are wearing blue shorts. Some of the students are girls and the rest are boys. The ratio of the number of girls wearing blue shorts to the total number of students wearing blue shorts is 3:5. How many girls are wearing blue shorts? How many boys are wearing blue shorts?

27 girls are wearing blue shorts.

18 boys are wearing blue shorts.

Step-by-step explanation:

5/7 of the 63 students in gym class are wearing blue shorts. This means that the total number of students in the class wearing blue shorts is

5/7 × 63 = 45 students

The ratio of the number of girls wearing blue shorts to the total number of students wearing blue shorts is 3:5

If the number of girls wearing blue shorts is x, then

x/45 = 3/5

Cross multiplying, it becomes

x × 5 = 45 × 3

5x = 135

x = 27

The number of boys wearing blue shorts would be

45 - 27 = 18

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
