Answer:

Step-by-step explanation:

Given that your friend tossed a fair coin when you weren’t around.

Let A be the event that she said the outcome is head

B1 = Event she lied and B2 = Event she did not lie

$P(B1) = \frac{1}{3} \\ P(B2) \frac{2}{3}$

P(AB1) = $\frac{1}{2} *\frac{1}{3} =\frac{1}{6}$

P(AB2) = $\frac{2}{3} \frac{1}{2} =\frac{2}{6}$

Required probability = P(B1/A)= $\frac{P(B1A)}{P(B1A)+P(B2A)} \\=\frac{\frac{1}{6} }{\frac{1}{6}+\frac{2}{6}} \\=\frac{1}{3}$

You just take 100% and subtract the 24% that makes up 84. which gives you 76 and u just multiply that by 84.
