Answer:
a) P = 2/7
b) P = 4/7
c) P = 1/7
Step-by-step explanation:
In the range of [2,8], we have the following integers which are: 2, 3, 4, 5, 6, 7, 8. So this is a total of 7 integers.
a) We look for the probability that the numbers are less than 4, so we conclude that there are possible numbers 2 and 3 out of possible 7, so the required probability is equal to P = 2/7.
b) We look for the probability that the numbers are greater than 4, so we conclude that there are possible numbers 5, 6, 7, 8 out of possible 7, so the required probability is equal to P = 4/7.
c) Based on the previous two examples, we conclude that the required probability is P = 2/7· 1/2=1/7.
Answer:
I need sum more detail
Step-by-step explanation:
The probability is 4⋅3⋅2⋅1/10•9•8•7=(4/4)(6/0)/(10/4)=1/210 so the probability of selecting 3 red balls would be 1/210
We know that point M is a midpoint of segment RS, and line l passes through segment RS. Since l passes through RS at its midpoint, M, then we can declare that l is the bisector of RS. Your best answer is A since the above is the basic definition of a bisector.
Answer:
y = 3
Step-by-step explanation:
<em>*As seen in the photo, the fact that EF = GF and the bisector being there makes EH = HG.</em>
<u>5y + 10 = 28 - y</u>
<em>*Add y to both sides.</em>
6y + 10 = 28
<em>*Subtract 10 from both sides.</em>
6y = 18
<em>*Divide both sides by 6.</em>
y = 3
