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

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

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

$P(G)=0.475$
