A card is drawn from a standard deck of cards, not replaced, then another is drawn. What is the probability that both cards are hearts?

4% chance of them both being hearts

Step-by-step explanation:

2/52=0.038=0.040x100=4%

2 stands for the # of cards

52 stands for how many cards are in a standard deck

Hope this finds you well have a nice day/night :)

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.
