Ratio of girls to boys is 3:2....added = 5.....this means that 3/5 of the total students are girls and 2/5 of the total students are boys.
so if there are 50 students...
3/5(50) = 150/5 = 30 girls
2/5(50) = 100/5 = 20 boys
Answer:
Step-by-step explanation:
A solution is any value of a variable that makes the specified equation true. A solution set is the set of all variables that makes the equation true. The solution set of 2y + 6 = 14 is {4}, because 2(4) + 6 = 14.
Answer:
a. The probability of both balls are blue is
.
b. The probability of getting first red and second yellow ball is
.
Step-by-step explanation:
It is given that the box contains 14 red balls,12 blue balls,and 9 yellow balls. The total number of balls is

The probability is defined as

Probability of getting red ball = 
Probability of getting blue ball = 
Probability of getting yellow ball = 
It is given that a ball is drawn at random and the color is noted and then put back inside the box. It means first event will not effect the probability of second event.
a.
The probability of both balls are blue is

b.
The probability of getting first red and second yellow ball is

No?
good luck :D..........
