Question

Jennifer it's two pennies 105 times how many times can expect both going to come up heads

Answer 1

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
`(1)/(2) * (1)/(2) = (1)/(4)`
Thus the expected number of simultaneous heads is 105/4 or 26.25
