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

Explain how to write 50,000 using exponents. Answer can only be one number but the answer can have as much exponents as wanted
Oksana_A [137]
The examples of 50,000 written as an exponent are as follows (but not limited to):

500 * 10^2
50 * 10^3
5 * 10^4
0,5 * 10^5

Doublecheck (optional):

500 * 10^2 = 500 * 100 = 50,000
50 * 10^3 = 50 * 1000 = 50,000
5 * 10^4 = 5 * 10000 = 50,000
0,5 * 10^5 = 0,5 * 100000 = 50,000

Please help with this 2+4(5-8). step by step
igor_vitrenko [27]
NAMASTE

HERE IS YOUR ANSWER:

2+4(5-8)
We know, the BODMAS (bar, order, multiply, add, subtract) rule. so we will solve it as follows:


➡2+4(-3) (✔ 5-8= -3)

➡2+(-12) (✔ 4(-3)= -12)

➡2-12 (✔ +(-12) = -12)

➡ \boxed{-10}
