A school cotains 357 boys and 323 girls if a student is chosen at random, what is the probability that it is a girl

solong [7]

Answer:

$P(G)=0.475$

Step-by-step explanation:

From the question we are told that:

Number of boys $N_b=357$

Number of girls $N_g=323$

Total Number of students

$N_t=N_b+N_g$

$N_t=680$

Generally the equation for Probability of Choosing a Girl is mathematically given by

$P(G)=\frac{N_g}{N_t}$

$P(G)=\frac{323}{680}$

$P(G)=0.475$

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

joja [24]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
