Rolling Dice Roll two standard dice and add the numbers. What is the probability of getting a number larger than 9 for the first

Rudik [331]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

The sum is larger than 9, it means we have: 10, 11, and 12

To get the outcome is 12, we have only one way is that the two dice shows face-6. The probability to have 12 is:

P(12) = $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{36}$

To get 11, we have it two ways once dice shows face-5 and the other shows face-6 and vice versa

P(11) = 2* $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{18}$

To get 10, we have it three ways ( once dice shows face-5 and the other shows face-6 and vice versa , two dice show 5)

P(10) = 3* $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{12}$

So the probability of getting a number larger than 9 for the first time on the third roll is:

P(12) + P(11) +P(10 )

= $\frac{1}{36}$ + $\frac{1}{18}$ + $\frac{1}{12}$ = $\frac{1}{6}$

It is reported that 32% of shoppers use cash to pay for their purchases. Based on this report, if a store has 250 sales in one d

Brilliant_brown [7]

The answer would be B) 80
To find the answer you would use the equation x/250 = 32/100. Then, you would cross multiply (multiply diagonally). This would leave you with 100x=8000. Finally you divide by 100 on n=both sides of the equal sign, leaving you with x=80.
