I haven’t studied this in school please can someone help

Step-by-step explanation:

The probability of rolling a 1 is 0.85; then the probability of rolling not 1 is

1 - 0.85 = 0.15

Each box that states rolling a 1 gets 0.85. Each box that states not rolling 1 gets 0.15.

                                   second

                first              roll

                roll            

                             /     0.85   1

       1        0.85 /

                           \    0.15     not 1

                             /  0.85   1

not 1           0.15

                         \

                            \    0.15     not 1
