Jennifer has two pennies. She flips both pennies 105 times each. How many times can she expect both pennies to come up heads simultaneously?

Assuming I have correctly interpreted your question,
The probability both coins come up heads is $\frac{1}{2} * \frac{1}{2} = \frac{1}{4}$
Thus the expected number of simultaneous heads is 105/4 or 26.25

Can someone give me some tips of how to study. I have already tried writing everything in my lesson but it doesn't seem to work

Ainat [17]

Study all notes, reread the chapters again. Have someone ask questions on the chapters page by page. This always has worked for me. Plus try to do this again the night before the test. You will be surprised how much you can remember by doing it again the night before the test. Hope this helps.
