So you know that 3^4 is your numerator and that is (4)(4)(4)(4)=81
3^2 is your denominator and that is (3)(3)=9
81/9
=9
Like I said above, There were 40 rolls, 6 of which were a two (6/40) and 8 of which were a 4 (8/40). Simply add these together to get 14/40 as the probability of rolling a 2 or 4. This simplifies to 7/20
Step-by-step explanation:
7-4 =33333333333333333333
Its C. becuase the sum of probabilities must be 1
1. 3^3 = 27, 27 x 270 = 7,290m^3
2. original volume = 8 x 6 = 48 cm^3
new volume = 48 x (5/4)^3 = 93.75 cm^3
