Step-by-step explanation:

the basic probabilty of being born with that certain trait is 5/9.

that means the probabilty of being born without that certain trait is 1 - 5/9 = 4/9.

the probability of 2 children being born with that trait and 3 being born without that trait is

5/9 × 5/9 × 4/9 × 4/9 × 4/9

but as you can see, this only covers a specific case, e.g. when the first 2 children have the trait, and the younger siblings don't.

for the general probability of that questioned result we need to multiply this with the number of different combinations : in how many ways can I pick 2 children out of 5, when the sequence of the 2 picked children is irrelevant ?

this is C (5, 2) = 5!/((5-2)!×2) = 5!/(3!×2) = 5×4/2 = 5×2 = 10

so, the probability is

10×(5/9)²×(4/9)³ = 10×5²×4³/9⁵ = 0.270961405...

≈ 0.271

each unit square of a 3-by-3 unit-square grid is to be colored either blue or red. for each square, either color is equally like
makkiz [27]

The probability of obtaining a grid that does not have a 2-by-2 red square 16 2/3%

probability : The probability of an event can be calculated by means of probability formula via honestly dividing the favorable quantity of outcomes by way of the total variety of viable consequences.

<u>Step-by using-step clarification:</u>

<u>given that:</u>

form are both square or circle with both equally likely :

for this reason,

P(square) = half of ; P(circle) = half of

color are either blue, pink or inexperienced with the 3 equally likely ;

P(purple) = 1/3 ; P(green) = 1/three ; P(blue) = 1/three

chance of creating a inexperienced circle :

independent probability

P(green n circle) = p(inexperienced) * p(circle)

P(green n circle) = 1/3 * half of

P(green n circle) = 1/6

= 0.16666

(0.16666 * 100%) = 16.6666%

= 16 2/3%

In still water, a boat averages 12 miles per hour. It takes the same amount of time to travel 14 miles downstream, with the curr
anyanavicka [17]
T is equal in both situations ... d = r X t   so d/r = t
c is rate of waters current

\frac{14}{12+c} = \frac{7}{12-c}
14(12 - c) = 7(12 + c)
2(12 - c) = 12 + c
24 - 2c = 12 + c
12 = 3c
4 = c     The rate of the waters current is 4 miles per hour.
