Answer:

Probability = 0.12

Step-by-step explanation:

Given : A drawer contain  4 red, 3 white , 3 blue socks

Total number of outcomes(S)= 10

Favorable event for first sock(B) ={3 blue sock}=3

Probability of picking first sock which is blue = favorable outcome/ total number of outcome P(B) = 3/10

since replacement is there

therefore, total no of outcomes remain same = 10

Favorable event for second sock(R) ={4 red sock}=4

then, probability of picking second sock which is red =favorable outcome/ total number of outcome P(R) = 4/10

Now, probability that the first sock is blue and the second sock is red is

P(B and R)= P(B) × P(R) = 3/10 ×4/10 = 12/100 = 3/25

Probability of events = 0.12

The probability that the first sock is blue and the second sock is red is:
(3/10) * (4/10)=3/25.

Answer:

Like radicals are radicals that have the same number in the radical sign

So it would be 3√7 and 11√7 (reasoning is they both have a 7 underneath the radical sign)

For the second one Simplify: 35√11-√11

you want to subtract like normal 35√11-1√11, (since there isn't a number there we are going to put one)

35-1=34

34√11, You want to keep the √11, because it is like having like terms but instead of variables it is √

34√11

The third one: Simplify: 15√6+3√6

we want to do the same thing as the problem above so,

15+3=18

18√6, again you want to keep the radical the same

18√6

For the fourth one: 5√7+√7-2√7

you want to do one step at a time so

5√7+√7= 6√7 (again you would have a one in front of the √7, then you would keep your radicals the same)

Then you want to subtract that to your other one

6√7-2√7= 4√7

6-2=4, (again keep the radical the same)

4√7

For the last one

3√5*√10+11√5*√10-√5

You always want to multiply first as in PEMDAS

Lets take this one step at a time also

First 3√5*√10

When multiplying radicals you would multiply like normal

3√50 (√5*√10= √50)

3√50

Now lets do 11√5*√10

again √5*√10=√50

so 11√50

Now you are going to add your two answers together

3√50+11√50= 14√50 (you would add 3+11=14, keep the radicals the same)

Don't forget about your -√5

14√50-√5, this as simplified as you can get so your answer is

14√50-√5

I hope this helps you ;)

I need help on 18 and 19 PLS HELP ME ILY I WILL MARRY U I WILL LOVEEE U FOR ETERNITY
Dmitriy789 [7]

Oof, this is surely a tough one.  But, if I'm looking at this correctly, than I think you were in the right mindset when trying to figure both of them out.  Like, for #18, think about the formula; P(B|A) = P(A and B)/P(A).  So, based on the question, you can let not rolling a 1 on the blue cube be A, and rolling a 1 on the red cube be B.  Now, personally, I prefer using the decimals when heading into the equations, but I'll convert the product into a fraction for the instruction's sake.  0.02777777778 + 0.13888888889 = 1/6.  1/6 ≈ 17.7%.  You can do the same for #19, the overall outcome would be 5/6, which would be about 83%.  Now, that's just me really attempting my hand at it, I will say, Math is far from my strong suite.  But, in all honesty, I really am doing my best to help (and no, it's not because of what you offered, lol, more rather I want to help people who struggle with the same problems I do).  Anyways, I hope this helps, and if you need more information, or anything, just let me know!  Wish ya the best of luck!!  ^u^
