The scientists who were trying to explain the continent shapes, just like scientists today, are devoting much time, thought and effort to developing and substantiating ideas that will account for the available evidence. however, whenever a new idea is proposed, it almost always requires further work and modification. note that each idea proposed thus far regarding the continents has some explanatory power, but also has significant problems. how does the time required to develop and substantiate science ideas as illustrated in this story compare to what science textbooks convey about the time required to develop and substantiate science ideas?

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:
