The first four terms of a sequence are shown below: 9,5, 1, -3
Which of the following functions best defines this sequence?
Of(1) = 9, f(n + 1) = f(n) - 4; for n 2 1
Of(1) = 9, f(n + 1) = f(n) + 4; for n 2 1
Of(1) = 9, f(n + 1) = f(n) - 5; for n 2 1
Of(1) = 9,f(n + 1) = f(n) + 5; for n 2 1

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?
