If you flip 3 fair coins what is the probability that you’ll get all three tails

1/8

Step-by-step explanation:

The possibilty of getting tails in one flip is 1/2, and there are three events, so that's 1/2 three times. To find the probability of multiple independent events occurring, you would multiply them together, so in this case you would do: 1/2 * 1/2 * 1/2 which equals 1/8.

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.

answer:

a=9
