Answer:
7/30
Step-by-step explanation:
We first have 7 blue and 3 red out of 10, so P(1st ball is red) = 3/10
Now, we have pulled a red ball out of the bag, leaving us with 7 blue and 2 red out of 9 total balls.Then P(2nd ball is blue) = 7/9. Put this together, P(1st red AND 2nd blue) = 3/10⋅7/9 =7/30
Answer:
17.39%
Step-by-step explanation:
We can summary the question:
- Probability of students using Google chrome= 0.49
- Probability of students using other browsers = 0.51
So the probability that you need to pick 7 students to find 2 students using Google Chrome is:
P(G) = * ()() = 21*0.2401*0.03 = 0.1739 = 17.39%
I confused ! I don't get what your trying to say please explain better !
Answer: C— 9 m
Steps:
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 81
b = 9
