Answer:
The probability of 9 successes in 10 trials in the binomial probability experiment is 0.387
Step-by-step explanation:
In this question, we are asked to compute the probability of 9 successes in 10 trials , given that the probability of success is 0.9
Firstly we need to know which approach we are going to use to solve this problem. To compute this probability, the approach to use is the Bernoulli approximation. To use this, we need to know the probation failure.
We can represent this by let’s say q. The probability of failure q in this case is 1-p = 1-0.9 = 0.1
Let us figure out the Bernoulli expression here. It would look like;
nCx * p^x * q^(n-x)
Let’s impute the value properly, we have;
10C9 * 0.9^9 * 0.1^1
= 10 * 0.9^9 * 0.1 = 0.387
I think it is D since a square is a rectangle since it has 2 pairs of parallel sides and it is a trapezoid since a trapezoid only needs 1 or more pairs of parallel sides
These 2 patterns are somewhat similar. This is because Add 3 about 5 times and you would get 15. And in for add five about 3 times and you would get 15. The same answer for both of the patterns.
Hope it helps!
