Two coins were tossed 10 times. The results are shown below.
toss: 1 | 2| 3 | 4 | 5 | 6 | 7 | 8 | 9 | |10
results: hh | tt | ht | th | ht | hh | th | tt |TH | HT
What is the experimental probability that at least one of the coins landed on heads? Express the probability as a decimal.
a. 0.8
b. 0.2**
c. 0.6
What is the experimental probability that both of the coins landed on tails? Express the probability as a decimal.
a. 0.8
b. 0.2
c. 0.6**
Excuse me, this site is about helping people with their answers not lowlifes making fun of people. Please stop, thank you.

Rat King, you don't need to be so mean about it. I'm sure that Reiny has friends, I'm also sure that he/she is much older than 7. Oh yeah who are you to assume that Reiny has dolls.
btw you forgot to add a s after "friend" also instead of putting the number 1 why can't you just put the word one it only takes a few seconds, and your writing would make much more sense.
BYE!!!
btw everyone "Ms.Amaa" is not a teacher she is faking this and im not sure why. (teachers have a special badge you can see... she does not)
Ms.T is also not a teacher..... the only teacher here is bobpursley
L L L stop faking fake teachers
love bob not the fakes

Make a tree diagram for two coins that are tossed. Find the theoretical probability that at least one coin is heads. Express the probability as a decimal.
To make a tree diagram for two coins that are tossed, we start by drawing two branches that represent the two possible outcomes of the first coin toss: heads (H) or tails (T). At the end of each branch, we draw two more branches that represent the two possible outcomes of the second coin toss: heads or tails. This results in four possible outcomes: HH, HT, TH, and TT.
```
H T
/ \ / \
H T H T
/ \ / \ / \ / \
H T H T H T H T
HH HT TH TT HH HT TH TT
```
To find the theoretical probability that at least one coin is heads, we can count the number of outcomes that have at least one head: HH, HT, and TH. There are 3 such outcomes out of 4 possible outcomes, so the probability is:
3/4 = 0.75
Therefore, the theoretical probability of getting at least one head is 0.75.
