There is a fair coin (one side heads, one side tails) and an unfair coin (both sides tails). you pick one at random, flip it 5 times, and observe that it comes up as tails all five times. what is the chance that you are flipping the unfair coin?

0.9697

Step-by-step explanation:

given that there is a fair coin and an unfair coin.

(both sides tails)

Let B = all tails 5 times

A1- fair coin

A2 - unfair coin

P(A1) = 0.5 and P(A2) =0.5 (since each coin is equally likely to be selected)

Required probability

= Prob (unfair coin/all tails) =P(A2/B)

=

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
