Suppose the dial on the spinner is spun 2 times in a row.
Ivenika [448]

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.

Find the values of x and y given that ABCD is congruent to EFGH.
Kazeer [188]

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

A and B together can do a work in 6 days. If A alone can do it in 15 days. In how many days can B alone do it.
Nina [5.8K]

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

\frac{1}{A's rate} + \frac{1}{B's Rate} = \frac{1}{combined rate}

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
