Hello!
Each time, there will be a 1/2 chance of tossing a head. Therefore, we multiply our two probabilities.
1/2(1/2)=1/4
Therefore, we have a 1/4 or 25% chance of tossing two heads in a row.
I hope this helps!
Convert the mixed fractions into improper fractions and divide them to get them into decimals. Then see if pi is in between those numbers.
Ex: 2 3/4 = 11/4 = 2.75
x+7
------------------- =
x^2+4x -21
x+7
= -------------------
(x+7)(x-3)

= ---------- where x is not equal -7 and 3
