Answer:
Step-by-step explanation:
If we call x the number of correct questions obtained in the 9 attempts, then:
x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.
So, the p of x successes has the following formula.
Where:
n = 9
p = 0.6
We are looking for P(x<4)
By definition:
Then:
Answer:
Sinθ = 24/25
Step-by-step explanation:
Sinθ = Opposite/Hypotenuse
Solve for the opposite side using the Pythagorean Theorem.
Therefore, Sinθ = 24/25.
