cestrela7 [59]

Answer: $\frac{15}{56}$

Step-by-step explanation:

We have to select george but not nina with two other people

No. of ways selecting 2 two people knowing Geroge will be the third one is

$^6C_2$ (beacuse we have to exclude Nina)

And total no of ways of selecting 3 people out of 8 people is $^8C_3$

Therefore the required Probability is $\frac{^6C_{2}}{^8C_{3}}$

= $\frac{15}{56}$

Pepsi [2]

Answer:

$50 and

$30

Step-by-step explanation:

Question 1. Principal = $500

Rate = 5%

Time = 2yesrs

Interest = PRT /100

= 500 x 5 x 2 /100

= 5000/100

= $50

Interest = PRT/100

Principal P =$500

Rate = 3%

Time = 2 years

Therefore, interest =

500 x 3 x 2 /100

= 3000/100

= $30

Inscribe a circle in a unit square and to r= 1000 random.

Oduvanchick [21]

Step-by-step explanation:

area of square = 1

area of a circle in square = $\pi r^2 = \pi *(1/2)^2 = \frac{\pi }{4}$

bu estimate $p^ = X/n = 760/1000 = 0.76Therefore, 
[tex]\frac{\pi }{4} \approx 0.76$

$\pi \approx 0.76*4 =3.04$

b) if n tend to infinity

$\pi will approach 3.14$
