7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
The probability of not rolling a 2 is 5/6
Step-by-step explanation:
Given
Probability of rolling a 2 = p = 1/6
The probability is the chance of occurrence of an event.
Let q be the probability that the dice doesn't roll 2
The sum of probability of occurrence of an event and non-occurrence of an event is 1
So,
Putting the value of p
Hence,
The probability of not rolling a 2 is 5/6
