Answer:
The pythagorean theorem states that a² + b² = c².

We have a = 10 and c = 20.

100 + b² = 400

Subtract 100 from each side.

b² = 300

Get the square root of 300.

It could be expressed as b ≈ 17.321, or could stay in radical form as.

Hope this helps!

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

**Thus the expected number of simultaneous heads is 105/4 or 26.25**

Assuming I have correctly interpreted your question,

The probability both coins come up heads is
