Answer:
right by 3 I think
Step-by-step explanation:
Answer:
Given:
- Total balls = 10
- Black balls = 3
- White balls = 7
⇒ P(black ball) = 3/10 = 0.3
⇒ P(white ball) = 7/10 = 0.7
If one ball is chosen at random and <u>replaced</u>, the probabilities do not change between the first and second ball.
Let event D = first ball is black
Let event S = second ball is black
P(D) = 0.3
P(S) = 0.3 (since the first ball is replaced)
⇒ P(D ∩ S) = P(D) × P(S)
= 0.3 × 0.3
= 0.09
For Independent Events we know that: P(A ∩ B) = P(A) × P(B)
Therefore, as P(D ∩ S) = P(D) × P(S) the events are independent.
Answer:
1,030 quarts in two months
Step-by-step explanation:
First you would add the two months together like: 2,560 + 1,560 = 4,120
Then you would divide I think 4,120 by 4 which would look like: 4,120/4
You should get 1,030. I'm not sure if I did this right so rip ¯\_(ツ)_/¯
The answer would be 0.5 miles per hour. This is because to get from feet per hour to Miles per hour, you need to divide by 5280. (1 mile = 5,280 feet.)
