Find the probability of each event. A class has five boys and nine girls. If the teacher randomly picks six students, what is th

kumpel [21]

Answer: $\dfrac{60}{143}$

Step-by-step explanation:

Given, A class has five boys and nine girls.

Total students = 5+9=14

Number of ways to choose 6 students out of 14= $^{14}C_6$ [Using combinations]

Number of ways to choose 4 girls out of 6 (4 girls + 2 boys = 6 ) = $^{9}C_4\times\ ^{5}C_2$

If the teacher randomly picks six students, then the probability that he will pick exactly four girls:-

$\dfrac{^{9}C_4\times \ ^{5}C_2}{^{14}C_6}$

$=\dfrac{\dfrac{9!}{4!5!}\times\dfrac{5!}{2!3!}}{\dfrac{14!}{6!8!}}\\\\=\dfrac{1260}{3003}\\\\=\dfrac{60}{143}$

hence, the required probability = $\dfrac{60}{143}$ .

Question 1

$2(5y-2)=12+6y$

Distributing 2 on 5y -2, we will get

$10y-4=12+6y$

But student get

$7y-4=12+6y$

So the student make an error in step 2 .

Second question

$Equation \ P : y+z=6 \\ Equation \ Q : 8y+7z=1$

To get rid of y, we have to multiply first equation by -8 and add the resultant equation with equation Q .
