The probability of one success and one failure will be 4/9. Table C represents the probability distribution for the variable X.
<h3>What is probability?</h3>
The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,
The dials on the spinner are spun 2 times in a row.
P(dial lands on region)=P(success) = 2/3
P(failure) = 1/3
The probability that the two times dials on the spinner are not spun 2 times in a row.
P = (1/3)² = 1/9
The probability that the two times dials on the spinner are spun 2 times in a row.
P = (2/3)²= 4/9
One may calculate the probability of one success and one failure using the binomial distribution or by simply deducting the probabilities we previously determined from 1.
P = 1 - 1/9 - 4/9
P = 4/9
The probability of one success and one failure will be 4/9.
Hence table C represents the probability distribution for the variable
X.

Step-by-step explanation:
I'm good at math hehe ggggggrhdgcdg
Answer:
x=7 , y = 8.
Step-by-step explanation:
10x+65 = 135
or, 10x = 70
so, x = 7
Now,
4y-4=28
or, 4y = 32
so, y = 8
9 - 22 is -13 then add 12 yards equals -1 so they just lost one years from where they started so the answer is -1
Answer:
10 days to complete
Step-by-step explanation:
for mixed rate problems, the sum of each individual reciprocal rates equals the sum of the combined rate
i.e

we are given,
A's rate = 15 days to complete
Combined rate = 6 days to complete
B's rate = need to find
substituting' the given info into the equation above,
1/15 + 1/ (B's Rate) = 1/6
1 / (B's Rate) = 1/6 - 1/15 (convert right side to same denominator)
1 / (B's Rate) = 5/30 - 2/30
1 / (B's Rate) = 3/30
1 / (B's Rate) = 1/10 (taking reciprocal of both sides)
B's rate = 10 days to complete
