Scientific notation is a common way of writing very large numbers. in everyday life we
see this when dealing with cell phone storage. if a phone has 10 gigabytes of hard drive
space that means that it has 10x10' bytes of space. a megabyte is 1x10 bytes.

1. if our phone with 10 gigabytes of free storage downloads a game that takes of 76
megabytes, how much free storage is left?

2. describe the process of subtracting numbers in scientific notation and give the
solution.

3. discuss other place we frequently see scientific notation in real life?

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
