Bag 1:  2R, 1B

Bag 2: 1R, 1B, 2Y

Draw 1 from each bag

a) P(same color)

We have 2/3 chance of drawing R from bag 1 and a 1/4 chance of drawing R from bag 2

P(both R) = (2/3)(1/4)  = 1/6

We have a 1/3 chance of drawing B from bag 1 and 1/4 chance of B from bag 2

P(both B) = (1/3)(1/4) = 1/12

P(same color) =1/6 + 1/12 = 3/12 = 1/4

Answer: a) 1/4

b) P(exactly one R)

Same story except we look at the complement in bag 2

We have 2/3 chance of drawing R from bag 1 and a 1/4 chance of drawing R from bag 2, so a 3/4 chance of NOT drawing R.

P(1st red, second not red) = (2/3)(3/4) = 1/2

We have 1/3 chance of drawing B from bag 1, so 1/3 chance of drawing NOT red from bag 1.  We have a 1/4 chance of drawing R from bag 2, so

P(1st blue, second not blue) = (1/3)(1/4) = 1/12

P = 1/2 + 1/12 = 6/12 + 1/12 = 7/12

Answer: 7/12

How to solve the problem
Ksenya-84 [330]

Answer:

x=5

Step-by-step explanation:

∠D=∠E (angles opposite to equal sides are equal)

So, x^{2}=3x+10

    10=x^{2}-3x

    10=x(x-3)

we know 5×2= 10 & 5-3=2,

So, 10=5×(5-3)

      10=5×2

∴x=5

What is the answer to x+4=6
sattari [20]

Answer:

x=2

Step-by-step explanation:

When solving an algebraic equation, you have to get x alone

you do this by doing the inverse of whatever is efecting x

in this case it is x+4 so you subtract 4 from x+4

x+4-4=x

but when doing something like this, you have to do the same thing to both sides

x+4<em><u>-4</u></em>=6<u><em>-4</em></u>

x=2

please mark me brainliest!
