Liz tossed three quarters. Find P(heads, heads, heads).
I think it is 2/8.
3 quarters have 2 sides each. 2x3 is 6.
There is half a chance for heads so it is 3/6
Remember to always simplify.
3/6
=
1/2
Prob(HHH) = (1/2)(1/2)(1/2)
= 1/8
To find the probability of getting three heads when tossing three quarters, we need to find the ratio of the number of favorable outcomes to the total number of possible outcomes.
Each coin has two possible outcomes: heads or tails. So, the total number of possible outcomes when tossing three quarters is 2 * 2 * 2 = 8.
Now, let's determine the number of favorable outcomes (in this case, the number of outcomes where we get heads three times).
Since each coin toss is independent, the probability of getting heads on each toss is 1/2.
Therefore, the number of favorable outcomes is 1/2 * 1/2 * 1/2 = 1/8.
So, the probability of getting three heads is 1/8, not 2/8.
