Since the numbers are consecutive, they can be represented by:
x, x+1, x+2, x+3, x+4
Their sum is -20 = x+x+1+x+2+x+3+x+4. Result: -20=5x+10, or 5x=-30, or x = -6.
Then the numbers are -6, -5, -4, -3 and -2. These do add up to -20, as required.
The smallest of these is -6.

Solution 1.
Number of times the dice is rolled
= 11 + 22 + 7 + 8 + 13 + 19
= 80
Number of time 4 appeared = 8
Probability
= No. of preferred outcomes/Total number of outcomes
= 8/80
= 1/10
= 0.1
Solution 2.
Number of times the dice is rolled
= 11 + 22 + 7 + 8 + 13 + 19
= 80
Number of time 2 appeared = 22
Probability
= No. of preferred outcomes/Total number of outcomes
= 22/80
= 11/40
= 0.275
2s to expect if dice is rolled 400 times
= 0.275 × 400
= 110
I’m almost positive the answer is B
