8x -7(x+3)=12
8x -7x -21 =12
x -21 =12
x= 33

y = x + 3
y = 33+3
y = 36
(33,36)

8x-x+3=12
7x=9
X=1.3

April and Sanjay are both using tools to simulate the probability that a family with three children will have exactly one girl.

Oxana [17]

Answer:

Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes. As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.
