Elijah flipped a coin ten times. He expected to land on heads five times and land on tails five times. The coin actually landed on heads three times and tails seven times. What should Elijah do in order for his experimental probability to be closer to the theoretical probability?

Use 2 coins

Use a different coin

Only flip the coin two times

Repeat the experiment 100 times

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

is there answer choices?

1,8,15,22,29,36,43,50
