Its the third pair of inequalities
b 26 < n < 30
so n = 28
the 3 numbers are 28, 30 and 32
Answer:
The procedure results in a binomial distribution
Step-by-step explanation:
If all 120 couples used the YSORT method, it is fair to assume that the probability of a baby being a boy or a girl are constant through all trials (120 couples). Assuming 120 randomly selected couples, there is a fixed number of independent trials. Finally, since the babies can only be a boy or a girl, the binary condition is satisfied and thus, the distribution is binomial
150 divided by 25 equals 6. 6 times 3 equals 18. This means that you will spend $18 on gas each week.
