The sum of all the probabilities of outcomes of an event is equal to 1
2. A die has 1,2,3,4,5,6
P(4) = number of 4's/ total numbers
= 1/6
Multiply the number of roll's by the probability of getting a 4
100 *1/6 = 50/3 = 16 2/3
This is approximately 17
So the equation to begin with looks like this: 4(2x+5)-7, and once you solve it: (8x+20)-7, and then to 8x+13. Thus 8x+13 is your answer.
