A fair coin is flipped twice. Let X be the number of heads in the two tosses, and Y be the indicator r.v. for the tosses landing

kiruha [24]

Answer:

Step-by-step explanation:

It can be clearly observed that $X\in{0,1,2}$ and $Y\in {0,1}$

Now lets find the probabilities of all possible combinations

$P(X=0, Y=0)=P(Y=0|X=0)P(X=0)=0$

Since it is impossible that the coin ha flipped in different ways given that all the time the tail has fallen

$P(X=1,Y=0)=P(Y=0|X=1)P(X=1)=1\times2\times(\frac{1}{2} )^2$ =1/2

$P(X=2,Y=0)=P(Y=0|X=2)P(X=2)=1\times2\times(\frac{1}{2} )^2$ =1/2

and similarly,

$P(X=0,Y=1)=P(Y=1|X=0)P(X=0)=1\times(\frac{1}{2} )^2= 1/4$

$P(X=1,Y=1)=P(Y=1|X=1)P(X=1)=0$

$P(X=2,Y=1)=P(Y=1|X=2)P(X=2)=1\times(\frac{1}{2} )^2=1/4$

Answer:

B. g(t) = -16t² + 80t

Step-by-step explanation:

<u>Given function:</u>

g(t) = -16t² + vt + h

A model rocket is launched off the ground at an initial velocity of 80 feet per second.

<u>This gives us </u>

h = 0 and v = 80

<u>The function becomes:</u>

g(t) = -16t² + 80t

Correct option is B.
