Answer:
Step-by-step explanation:
Since x is a binomial random variable that counts the number of adults with at least a bachelor's degree, it means that there are only two outcome. It is either an adult has a bachelor's degree or not. The probability of success would be that the adult has a bachelor's degree. Therefore, probability of success, p = 20/100 = 0.2
Number of adults in the sample is 100
The number of success expected is x
We want to determine the probability of P(x ≥ 60)
Therefore, the most efficient way to calculate the probability that more than 60 adults have a bachelor's degree is
b. P(x<60)=binompdf(100.0.20.60)
This is because it is a discrete probability distribution function
Answer:
<em>15</em>
Step-by-step explanation:
Use the correct order of operations.
3[(11-6)^2÷5] =
= 3[(5)^2÷5]
= 3[25÷5]
= 3[5]
= 15
