The probability of an event - picking teams. About (a) 10 kids are randomly grouped into an A team with five kids and a B team w

LuckyWell [14K]

Answer: The required probability is $\dfrac{4}{9}$

Step-by-step explanation:

Since we have given that

Number of kids = 10

Number of kids in Team A = 5

Number of kids in Team B = 5

There are three kids in the group, Alex and his two best friends Jose and Carl.

So, number of favourable outcome is given by

$2(\dfrac{8!}{3!\times 5!})$

Total number of outcomes is given by

$\dfrac{10!}{5!\times 5!}$

So, the probability that Alex ends up on the same team with at least one of his two best friends is given by

$\dfrac{2(\dfrac{8!}{5!\times 3!)}}{\dfrac{10!}{5!\times 5!}}\\\\=2\times \dfrac{8!}{3!}\times \dfrac{5!}{10!}\\\\=\dfrac{4}{9}$

Hence, the required probability is $\dfrac{4}{9}$

May someone help me on this please what amount will I put for B?

Alborosie

P = $2000, Rate, r = 6% = 0.06 per year, Time, t = 5 years.

For compound interest compounded annually:

A) Amount, A = P(1 + r)^t

A = 2000(1 + 0.06)⁵

A = 2000(1.06)⁵ ≈ 2676.45

Amount ≈ $2676.45

<span>B) Interest = Amount - Principal </span>

= 2676.45 - 2000 = 676.45

<span>Interest ≈ $676.45<span> </span></span>
