Tom rolls a fair dice adds the results of each workout the probability of getting less than four

1/12

Step-by-step explanation:

Let’s list out cases:

1+1:

Probability of getting 1 and 1 is (1/6)^2 = 1/36

1+2:

Probabilty of getting 1 and 2 is (1/6)^2 = 1/36 and getting 2 and 1 is (1/6)^2 = 1/36.

That is all of the cases because 1+3 and 2+2 are equal to 4. Summing it up, we get: 3(1/36) = 1/12

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
