A pool is being filled with a large water hose. The height of the water in a pool is determined by 8g² + 38 – 4. Previously,
the pool had been filled with a different hose. Then, the height
was determined by 6g² + 2g – 1. Write an expression that
determines the height of the water in the pool if both hoses
are on at the same time. Simplify the expression

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?
