The number of points, x, scored in a game has the probability distribution below.

the number of points obtained in one game is independent of the number of points obtained in second game. when the game is played twice, the sum of the number of points for both times could be 0, 1, 2, 3, or 4.

if y represents the sampling distribution of the sum of the scores when the game is played twice, for which value of y will the probability be greatest?

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

step-by-step explanation:

other answer is correct. i had used the radius of the radius somehow. a website:

86

step-by-step explanation:

find the area of the triangle then multiply by 2 then add the area of the parollelegram multiplied by 2
