Answer:

19/20

Step-by-step explanation:

Probability of blue tile= 9/20

probability of letter b tile= 10/20= 1/2

Probability of blue or letter b= Probability of blue + probability of letter b

                                                 = 9/20 + 1/2

                                                 =   19/20
