Summer buys a bag of cookies that contains 7 chocolate chip cookies, 8 peanut butter cookies, 5 sugar cookies and 7 oatmeal cookies. What is the probability that Summer reaches in the bag and randomly selects 2 oatmeal cookies from the bag? Round your answer to four decimal places.

her chance of getting otmeal cookies are 7 out of 20

Step-by-step explanation:

you can round yourself

step-by-step explanation:

ask goog great chance of finding the solution there

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.
