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.

B. 11t/=250
THey earned a total of 250 dollars and so if each ticket cost 11 dollars if you multiply how much tickets they sold then you would get 250
Answer:
A = 210 cm²
Step-by-step explanation:
Perimeter of the triangle = the sum of the sides of the triangle.
70 = (3x - 1) + (4x + 1) + (3x)
70 = 10x
7 = x The length of the sides of the triangle are 3x - 1 = 20; 4x + 1 = 29 and
3x = 21.
Looking at the given information, this triangle is a special type of triangle because the area of a triangle is Area = 1/2 bh and you do not know which side is the base and height of the triangle.
Trying a² + b² = c² to see if it is a right triangle. 20² + 21² = 29 ² ; yes it is a right triangle and now we know that the base and height is 20 and 21. The longest side is the hypotenuse in a right triangle
A = 1/2bh
A = 1/2 (20)(21)
A = 10 · 21
A = 210 cm²
