Four girls and six boys are in a Spanish club. Three of the people will be chosen at random to represent the group in a photogra

snow_tiger [21]

Answer:50 %

Step-by-step explanation:

Given

There are 4 girls and 6 boys in a club

Probability of choosing 1 girl and 2 boys is

$=\dfrac{\text{No of ways of choosing 1 girl and 2 boys }}{\text{No of ways of choosing 3 member out of 10 member}}$

No of ways of choosing 1 girl and 2 boys $=^4C_1\times ^6C_2$

$P=\dfrac{^4C_1\times ^6C_2}{^{10}C_3}$

$P=\dfrac{4\times 15}{10\times 3\times 4}$

$P=\dfrac{15}{30}=\frac{1}{2}$

i.e. $50\%$
