Answer:
50%
Step-by-step explanation:
assuming you are talking about one coin flip (because you didn't specify) you have a 50% chance to land on tails
This cannot be the question. You definitely read this wrong. If p(notA)= .75 then P(not A) = .75...
If the question is find P(A), however, then the use the compliment rule
1- P(not A) = P(A)
1-.75 = .25
Use the cosine rule.
c=AB=7
b=AC=8
a=BC=3
a^2=b^2+c^2-2bc(cos(A))
=>
cos(A)=(b^2+c^2-a^2)/(2bc)
=(7^2+8^2-3^2)/(2*7*8)
=13/14
=0.9286
