Help plz i’ll give extra points f

First Option | 2 x 10^1

Reason: After doing 6.4 divided by 3.2, you get 2, and finally you subtract 10³ by 10². And after that subtraction, you get 10^1, Therefore the answer is the first option.

I hope this helps, and Happy Holidays! :)

Number 1: First of all: You can expect it to roll a 6 7 times. Why? If you roll a cube 42 times, and there are 6 possible outcomes, the theoretical probability of rolling each number is rolling it 7 times. 

Number 2: take 92/100 and compare it to 540/?
Divide 540 by 100, and you get 5.4 . Then, multiply 5.4 by 92, and then you get 496.8. If they want at least 92% alive, they should order at least 497 plants.
