The possibilities are HH TT HT TH so to get TT you have a 1/4 chance (25%)
Answer:

Step-by-step explanation:
Given
Represent Boys with B and Girls with G


Required
Find the probability or having 1 boy 2 girls
Since the order is not important, the probability is calculated as follows;

Substitute
for P(B) and P(G)



<em>Hence, the fractional probability is </em>
<em></em>
<em></em>
The polygon would have 18 sides. Hope this helps!
SINCE the slope is -2 it would be like this -2/1 but first plot the y-intercept onto the graph and go down 2 and over 1.
Angles UST and TSU are equivalent.
The answer is TSU
