Let's call the event of the red die to show a six as event A, and the event of the green die to show a six as event B.
The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes. On both dices, we have 6 possible outcomes(the numbers from 1 to 6), with one favourable outcome(the number 6), therefore, the probabilities of those events are:

Each roll is independent from each other, then, the probability of both events happening simultaneously is given by their product:

Using the additive rule of probability, we have the following equation for our problem:

the probability that the red die shows a six or the green die shows a six is 11/36.
2x+5=47, solve algebraically to find x, the answer
Answer:
The value of given expression is 19.
Step-by-step explanation:
The given expression is

According to the rule of BODMAS the order of operations is Bracket, Of, Division, Multiplication, Addition and Subtraction.
First we have to simplify the value of bracket.


Therefore the value of given expression is 19.
