Part A
P(white) = (3 white)/(10 total) = 3/10
<h3>Answer: 3/10</h3>
==============================================
Part B
10 total, 3 are white
10-3 = 7 are not white so they are either black or red
P(black or red) = 7/10
<h3>Answer: 7/10</h3>
==============================================
Part C
Earlier in part B we calculated 7 beads that weren't white
This means P(not white) = P(black or red) = 7/10
They are the same probability just phrased slightly different ways.
<h3>Answer: 7/10</h3>
==============================================
Part D
There aren't any blue beads (unless there's a typo somewhere). So the probability of picking not blue is 100% or we represent this as the value 1.
<h3>Answer: 1</h3>
Answer:
Step-by-step explanation:
7/8) / (1/2) .when dividing fractions, flip what u r dividing by, then multiply
7/8 * 2 = 14/8 = 1 3/4 <==
Answer:
9 mm wide
Step-by-step explanation:
Perimeter = length x 2 + width x 2
34 mm = 16 mm + ?
34mm = 16 mm + 18 mm
18/2 = 9
9 mm wide
Answer:
p = -2
Step-by-step explanation:
O we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
