Answer:
1/6
Step-by-step explanation:
There are six possible numbers that can be rolled twice.
1/6 x 1/6 = 1/36
by the rule of the product.
Since this can happen for 2,3,4,5,6, as well as for 1,
the probability of rolling the same number twice is
6⋅1/6⋅1/6=1/6
<span>(12.67 + 19.2)(3.99) / (1.36 + 11.366) = 31.87(3.99) / 12.726 = 127.1613 / 12.726 = 9.992</span>
