1. What is the ratio of black to white squares? (1 mark)
I

im sure it would be 2:4. if it was to be simplified it would be 1:2

2 : 4

1 : 2

black to white squares

theirs 2 black squares and 4 whites

put 2 first because its (black) to white

so we would have 2 : ? now we add the four to the other side

now we have 2 : 4

to simplify it we can half both sides witch will get us 1 : 2

probability for j is 1/4

while

a is 1/6
