The statement that is true regarding the sides of a triangle is the last one because the top and bottom have to be identical to each other and the sides have to be identical to each other.
The correct answer is .05
To solve, find the decimal of each of the probabilities:
Flipping Tails: 1/2 ----> .5
Picking 3: 1/10-----> .10
Now, multiply them together:
.5 x .10 = .05
Hope this helps!
