Coin is tossed 10 times and lands tails up 3 times. What is the experimental probability of the coin landing tails up? Experimental Probability (tails) =

The coin is tossed 10 more times. Out of 20 total tosses, the coin has now landed tails up 8 times. Calculate the experimental probability of the coin landing tails up, taking this new data into account.
Experimental Probability (tails) =

The coin is tossed 10 more times. Out of 30 total tosses, the coin has now landed tails up 15 times. Calculate the experimental probability of the coin landing tails up, taking this new data into account.
Experimental Probability (tails) =

What is the theoretical probability of the coin landing tails up?
Theoretical Probability (tails) =

The experimental probability will approach the theoretical probability as more trials are performed.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.
