Suppose we pick three people at random. For each of the 2.32 The following questions, ignore the special case where someone migh

Fantom [35]

Answer:

Step-by-step explanation:

Given that we pick up three people at random.

We can ignore the leap year so we assume there are 365 days in a year.

Probability for a person to be born on a specific data is equally likely and hence equal to

$\frac{1}{365}$

Each person out of three persons is independent of the other.

Hence for the second person to have the same birthday would have equal probability.

X = No of persons to have common birthday is binomial with n =3 and p = $\frac{1}{365}$

a) the probability that the first two people share a birthday

= $(\frac{1}{365})^2\\= \frac{1}{133225}$

b) the probability that at least two people share a birthday

= $P(X\geq 2)\\=P(x=2)+P(x=3)\\= 3C2 (\frac{1}{365} )^2*\frac{364}{365}+(\frac{1}{365})^3$

Write the equation of the line.

kotykmax [81]

Answer:

y = 4

Step-by-step explanation:

Since the line in question is parallel to the x axis, we can tell that going from one end of the line to the other, x value changes, but y value always stays the same and equals 4.

PLEASE HELP!! 100 POINTS Will mark brainliest.

AnnyKZ [126]

Answer:

m∠1 = mCD = 40°
m∠2 = 1/2(mAB) = 1/2*30° = 15°
m∠3 = 1/2(mED) = 1/2*50° = 25°
m∠4 = 1/2(mAB + mDE) = 1/2(30°+50°) = 40°
m∠6 = m∠OEG - m∠DEG = 90° - 1/2(mDE) = 90° - 25° = 65°
m∠7 = 1/2(mCD + mDE) = 1/2(40°+50°) = 45°
m∠8 = 1/2(mCD + mDE - mAB) = 1/2(40° + 50° - 30°) = 30°
m∠10 = 1/2mAE = 1/2(180° - mDE) = 1/2(180° - 50°) = 65°

Answer:

D. 13*3^x

Step-by-step explanation:

$3^x +4*3^x^+^1= \\3^x+4*3(3^x)=\\3^x(1+[4*3])=\\3^x(1+12)=\\3^x(13)=\\13*3^x$
