Rocco rolls two number cubes at the same time. what is the probability of rolling a 2 and 3\

The probability of getting a 2 and 3 in two cubes is

Explanation

Total face values in each number cube is  6.

In first cube, probability of  getting a 2 is =

and also in the second cube, probability of getting a 3 is =  

So, the probability of getting a 2 and 3 in two cubes =

practice. practice. practice.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
