Answer:
There are 2 items in the complement of b
Step-by-step explanation:
Complement of a set is all items not in the set
Complement of set b is all numbers less than and including 2
Since the sample space is 1,2,3,4,5
The only numbers in the complement of b is 1,2
6i =6 (cos 3n_2 +i sin 3n_2
The probability that fewer than 4 of them are successful are 0.9527
<u>Explanation:</u>
Given:
number of trials, n = 6
p(successful) = 0.85
P(x >= 4) = ?
The problem can be solved using binomial probability formula.
P(x >= 4) = 1 - binomcdf(6,0.85,4) = 1 - 0.0473
= 0.9527
Therefore, the probability that fewer than 4 of them are successful are 0.9527
