Question

tamara finds the sum of two number cubes rolled at the same time. the chart below shows all possible sums frim thr 36 possible combinations when rolling two number cubes. how many times should tamara expect the sum of the two subes to be equal to 4 if she rolls the two number cubes 252 times?​

Answer 1

Im notr sure but if we take the chances that the 4 sum has to be either (1.3) (3.1) (2.2) (2.2) that means its chance is 4/36 for each roll which is also 1/9 ,, we can multiply 1/9 times the roll times ( 252 ) we get =28
