Is there a function in R for discrete probability distribution?

I have a set of Bernoulli variables, giving specific values with different probabilities. The variables are independent. I'm trying to build a simple discrete probability table for all the possible outcomes. A short example of the data I have is:

# A tibble: 2 x 4
  `test number`  prob value `no-value`
          <dbl> <dbl> <dbl>      <dbl>
1             1   0.7   1.7        0.3
2             2   0.6   1.5        0.6

and the solution I'm trying to find is:

# A tibble: 1 x 5
  value       `3.2` `2.299999999999999~ `1.8` `0.8999999999999999~
  <chr>       <dbl>               <dbl> <dbl>                <dbl>
1 probability  0.42               0.280  0.18                 0.12

Where the value is the sum of the possible values and the probability is the probability of this value.
