Answer:
y-1+ 2y^2/y^3+1
Step-by-step explanation:
There are two choices for each child: overweight (o) or underweight (u). So if the first child is o the next can be o or u. If the first is u the second can be o or u. This gives four possibilities. Here the first child is the letter noted first and the second is the one listed second:
OO
OU
UO
UU
There are 4 outcomes and if each is equally likely then the probability of each is 1/4. Thus the probability of UU is 1/4
The probability of one underweight and one over weight is 1/2 because in two of the outcomes listed above there is one O and one U (namely OU and UO). Since there are 4 outcomes the probability is 2/4 = 1/2
Answer:16
Step-by-step explanation: 3 over 4.5 = x over 24
Cross multiply and you get 4.5x=72
72/4.5= 16
Answer: n=3
Step-by-step explanation:
Divide by - 2
(N+3) = 6
Subtract 3
N= 3
