Answer:
Step-by-step explanation:
a. This is a binomial probability distribution problem expressed as:
Where:
- is the probability a successful event.
- the number of successful events.
- is the total number of events.
Given n=10, p=0.47 the probability of exactly 5 is calculated as:
Hence, the probability that exactly 5 adults have very little confidence is 0.2417
b. Given n=10, p=0.47,
-We substitute our values in formula and the probability of at least 6 is calculated as:
Hence, the probability of at least 6 adults is 0.3056
c. The probability of of less that four adults is calculated as:
Hence, the probability that less that 4 adults have confidence in the newspapers is 0.2255

Answer:
65
Step-by-step explanation:
use the following equation
aₙ=a₁+(n-1)d
Where d is the common difference
n is the term
a₁ is the first term
the common difference is -3 (149-152)
this means we have
152+(30-1)*-3
Compute this and get
65
