X=3.1:
Step-by-step explanation:
Answer:
X ~ B(n, p)
Given: X ~ B(2, 5/17)
⇒ n = 2
⇒ p = 5/17
Binomial distribution formula:

As n = 2, calculate P(X = 0), P(X = 1) and P(X = 2):

Answer: The third option is correct
Step-by-step explanation: With increased trials, experimental probability will grow closer to theoretical probability. Blue pens make up 1/2 of the probability pool.
Answer:
22.5
Step-by-step explanation:
You just have to do 60 divided by 2.66 (The decimal form of 2/3) and then you have your answer PLEASE BRAINLIEST
3/4 = 9/12
2/3 = 8/12
9/12 - 8/12 = 1/12
So Johnny ran for 1/12 of an hour longer than Angie.
