Tom rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 4.

what is the rest of the question? ?

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
