Jeremy randomly selected a round tile and a square tile from the sets shown below. what is the probability that jeremy

selected either two blue tiles or two white tiles?

a. 23/26

b. 4/9

c. 7/72

d. 1/40

b. 4/9

Step-by-step explanation:

The probability of selecting either two white or blue tiles and square and round tile is 4. The two white tiles could either be square and round, square, round, or the white tiles could be either square and round, round or square. Each tile has four possible outcomes blue,white, square,round.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
