Can someone answer this math probability question?
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?

1) (1/2)(1/2)(1/2) = 1/8 2) with two die P(sum < 10) = 30/36 = 5/6 P(sum = 5) = 4/36 = 1/9 If it means the first die is less than 10 = 36/36 Second is five = 1/6 3) 3/8 4) 1/2 5) (7/8)(1/8) = 7/64
