We should each take these probabilities first individually.
Probability of tails in a coin toss = 1/2
Probability of <span>drawing letter T from the alphabet = 1/26
Probability of 2 tails in 2 coin toss = 1/4
Sample space = {HH, TT, HT, TH}

Add these together since these events happen after another = 1/2 + 1/26 / + 1/4 = 41/52

The final probability is 41/52</span>

AD is the angle bisector of ∠EAB. Solve for x. ANSWERS:
Fofino [41]

Answer:

D)  6.4

Step-by-step explanation:

The Angle Bisector Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

This means that:

18/9.6 = 12/x

Solving for x:

x = 12*9.6/18

x = 6.4
