Marta_Voda [28]

Answer:

c. 0.3421

Step-by-step explanation:

The computation of the probability of selecting the biased coin is shown below:

The probability of any coin selected is 1 ÷ 2

The probability in the case when the biased coin chosen & wins 1 ÷ 2 (1 - 0.74)

And, the win probability is 1 ÷ 2  (1 - 0.74) + 1 ÷ 2  (1 - 0.5)

Now the probability of biased or win is

=  {1 ÷ 2 (1 - 0.74)} ÷ { 1 ÷ 2  (1 - 0.74) + 1 ÷ 2  (1 - 0.5)}

= 0.13 ÷ 0.38

= 0.3421

Hence, the correct option is c. 0.3421
